Coding the Displaced Frame Difference for Video Compression
Popular techniques employed to code the Displaced Frame Difference (DFD) treat it no digerently from an ordinary image for coding purposes. Since the DFD is generated by the process of motion compensation, such methods do not fully exploit the underlying redundancies. This paper is aimed at proposing a DFD coding method which exploits such redundancies while incurring negligible information ove...
متن کاملVideo Object Segmentation Based on Accumulative Frame Difference
This paper addresses the problem of extracting video objects from head−shoulder video sequences. A method based on accumulative frame difference is proposed. First, a preliminary motion analysis is performed to each block of the frame and the blocks with fast moving edges are detected. Then, for each block, we accumulate frame difference with a different amount of frames, based on its motion at...
متن کاملThe Key Frame Extraction Algorithm Based on the Indigenous Disturbance Variation Difference Video
In view of the traditional support vector machine (SVM) learning algorithm’s learning parameters is not easy determined in the process of video key frame extraction and the accuracy is low, an independent perturbation variable difference SVM algorithm is used for video key frame extraction. First of all, analyzed the biological mechanism of differential evolution algorithm, put forward an impro...
متن کاملRFCAVLC8t: a Reference Frame Compression Algorithm for Video Coding Systems
This paper presents the Reference Frame Context Adaptive Variable-Length Compressor eight tables (RFCAVLC8t) for video coding systems. RFCAVLC8t aims to reduce the external memory bandwidth required to carry out this process. Six experiments were performed, all based on adaptations of the Huffman algorithm, and the best experiment achieved an average compression rate of more than 30% without an...
متن کاملDetecting Moving Targets from Traffic Video Based BSFD: Background Subtraction Frame Difference Algorithm
Advantages and drawbacks of two common algorithms often employed in the moving target detection, background subtraction technique and frame distinction methodology are analyzed and compared during this paper. Then supported the background subtraction methodology, a BFSD target detection rule is projected. The background image used to process the next frame image is generated through superpositi...
