Abstract
Owing to the rapid growth of multimedia technology, multimedia information is easily accessed by any user and the same information construction and distribution are also very easy. Due to technology development, the multimedia information increases due to variety of factors: it can be uploaded by unprofessional users nowadays. Due to the low quality and the large number of duplicated video files available, this leads video extraction more and more complex. The general method of representing each video segment is shot that consists of series of frames. Among this series, the input frame based shot method is specifically assisted for searching the video content as clients provided image query/search where an image will be matched with the indexed key frames with assist of resemblance distance. As a result, the key frames selection is most significant, and several methods are used to automate the process. This paper proposes a new technique for key frame selection. The proposed method shows significantly good and the experiments prove the above statement.

1 Introduction
Data mining is a process of detecting knowledge from a given huge set of data. Of the available huge data set, multimedia is the one which contains diverse data such as audio, video, image, text and motion, and video data play a vital role in the field of video data mining. In short, the application of video data is called video data mining. Data mining helps the users to retrieve the efficient content using data mining preprocessing operations. Increasing the quantity of video content reduces the quality of the content; flexibility of the network produces duplicated information. Technology brings the huge amount of multimedia data sets. From this data set it is very difficult to the user, extract the needed informaton. For reduce the burden (Searching) data mining helps remove the unwanted infromation from the given data set. Nowadays, information is shared in the form of images instead of text information. Technology allows the users to share and upload this information in an easy manner. For retrieving these multimedia content such as image and motion, pixel values are quite difficult. This brings today most challenging operations for both users and researchers. While some basic forms of multimedia retrieval are available on the Internet, these tend to be inflexible and have significant limitations. The key frame selection is having two main issues: 1. The number of key frame(s) utilized, (The first issue is tackled by where the amount of key frames for every shot will be decided arbitrarily using the shot length). 2. The significant representative frame(s) selection in a shot. (The second issue is generally complicated for choosing the frames automatically with maximum semantic value. This issue is handled through minimizing the redundant frames with the help of the methods, for example, relevance ranking). Existing methods for searching video to identify co-derivatives have substantial limitations: they are sensitive to degradation of the video; they are expensive to compute; and checking the whole video files is quite complex, and also comparing the entire video content is not possible. Existing techniques perform direct comparison of video features between the query clip and the data being searched, which is computationally expensive.
2 Existing System
-
There is no proper indexing and retrieval process available. Existing indexing techniques are suitable for only few sets of video files.
-
Vast amount of video files are currently available on the web. There is not proper mechanism to arrange these contents. Proper arrangement reduces the searching time of the user.
-
Current technique focuses on text-to-image retrieval; it never produces good result. Every search engine never returns the same type of information even if the users’ query may be the same.
2.1 Drawback of Existing System
-
This approach does not consider about the false positives and false negatives in the given video.
-
The fault tolerance value is not reduced.
-
Incorporating genetic variations into the design will affect the accuracy of this work.
-
It considers only the action-based video mining.
-
Human motion detection specifies only a particular region.
2.2 Advantage of Proposed System
-
Compared to other search method, this method can also reduce the detection time.
-
It first pre-processes the query image and extracts the features of that image.
-
Trained videos are stored in the database, and the features of the trained videos are clustered using the extracted features of the query input image.
-
Finally, features matching procedure is implemented to identify the similar features and to retrieve the relevant video.
-
This method provides an efficient video retrieval using an image as input.
-
Efficient clustering process is implemented.
-
Features matching provides an efficient and accurate similar video retrieval
3 Literature Survey
Effective Multimedia Content Retrieval [1]. This paper brings the effective multimedia content retrieval using hierarchical clustering algorithm. Clustering provides grouping the data set effectively; it also reduces the searching time. Real-Time Human Pose Recognition in Parts from Single Depth Images [2]. The problem of predicting the human pose recognition in parts in a single depth image is discussed here. A new method should be proposed to quickly and accurately predict the position of the body joints from a single depth image. In Video Mining with Frequent Item set Configurations, [3] a new method for mining frequently occurring objects and scenes from videos is proposed. Object candidates are detected by finding recurring spatial arrangements of affine covariant regions. Content Based Image Retrieval using Color Histogram; [4] this paper brings the information retrieved based on the content; image can be extracted using image features such as text, pixel value, motion, frame value. Here, they proposed image feature vector technique, construct color histogram. An enhanced technique based on content-based image retrieval and video indexing [5]; this paper brings the new indexing technique for video data file using one of the image features like color. With the help of global color histogram (GCH) and histogram analysis, they create an indexing operation.
4 Experimental Setup
Experimental setup consists of a four-step operation. First, creation of an admin database; here, video frames are converted as shots, and those values are stored in the database [6]. Followed by users’ image query, here, user input frames are taken, whose values are compared with existing stored value, and then, creation of key frame indexing; it reduces the searching time. The last phase called video retrieval is the process of user input frame matched with stored value, and similar value returned to the user. This experiment is conducted for various video files such as song, game, debate, news, and animated sets of video files. The entire process is constructed and tested using JAVA coding. Experiment is conducted as: for each video file, one input frame is selected, and then, based on the input, output extractions are done.
4.1 Creation of Admin Database
Key frame selection process is done with a two-step process. First phase called training phase or user side phase. The second phase is input query phase or server side phase. In the first phase, video files are converted as frames; after successful elimination of duplication frames, frames histogram values are calculated and stored in the admin database. Using file handling method, the duplicate files are eliminated. Key frame is determined by the frame that is the most same to the average frame. In the second phase, user input query; here, user input frame is compared with our stored frame value. Frames those are matching with input frame are extracted and returned to the user (Fig. 1).
4.1.1 Video Training Set Algorithm
-
Step1: Select input video file.
-
Step2: Segment the input file extract frames.
-
Step3: Eliminate duplication using image histogram technique.
-
Step4: Select key frames.
-
Step5: Per from Client and Servicer side operations.
-
Step 6: Based on users input, do video frame matching.
-
Step7: Retrieve and send matched result.
4.2 User’s Image Query
Fine matching stage is specially designed to choose which image in the image database is the most relevant one with that of the query image. Also, the measure to signify the degree of similarity has to be described. In this phase, input query image features are extracted using image feature extraction [7]. Extracted value is compared with admin-stored database values. The matching frames are returned to the user (Fig. 2).
Pseudo code for duplication removal:
Grey value = lngGrayScaleValue = (0.299 * clrPixel.R) + (0.587 * clrPixel.G) + (0.1114 * clrPixel.B)
Grey = Σ Grey value
‘Grey’ gave the value of the grey value of the whole image.
Grey value = Image1.Greyvalue – Image2. Grey Value
If Grey value < threshold then Duplicate Image
4.3 Video Frame Retrieval
Image retrieval is done with various techniques like histogram, image indexing, and algorithmic techniques. Indexing is the process to improve the performance and to reduce the searching time. Frame retrieval consists of the following steps:
-
Step1: Select the input frame.
-
Step2: Calculate the pixel value of input frame.
-
Step3: Convert the value obtained in Step2 into histogram value.
-
Step4: Compare this value with the existing value stored in the database (Fig. 3).
4.4 Creation of Key Frame Indexing
Due to the availability of video content in the web, it is very difficult to organize and retrieve the content. Increasing the usage of video data file, today, it is necessary for video data indexing. Many number of indexing techniques are available today, but the experimental result shows that each technique supports a particular type of video files only. For this reason, improvement is needed in each methodology. Here, we proposed key frame indexing technique for image retrieval, and the experimental results prove that the proposed technique provided better results (Fig. 4).
5 Conclusion and Future Enhancement
This work brings out an efficient technique for video information retrieval. Because of the network development and its flexibility, the usage of image information has increased in recent years. This is because of the increasing demand for image information, and also, it provides very easy access to the video contents. Every day, the amount of these image files is increasing due to various factors like usage of mobile phones, twitter, facebook, YouTube and more. Creation and distribution of these files are very easy. Still, we suffer to manage and retrieve these contents. There are no efficient techniques or tools presently available. This paper brings the key frame image indexing technique for retrieving and efficiently indexing the video files. Results proved that the proposed method is more efficient.
5.1 Future Enhancement
The future enhancement of this technique by adding additional features will produce more accurate results.
