HEVC Encoding and Decoding using Fast Algorithm for Intra Frame Partition-Prediction Using DTCWT

Video compression techniques need to be robust, flexible and provide higher coding efficiency in order to meet the increasing demand of bit rate to support transmission and storage of high resolution videos. High efficiency video coding (HEVC) is significantly increasing the coding efficiency of its ancestor H.264/Advance Video Coding. Evaluation of partition-prediction algorithm proposed in this work is carried out by comparing the MSE and PSNR results with two other methods. The direct partition-predictionmethod andDWT-based partitionprediction method results are compared with the proposed results. Four different data sets are considered for evaluation, and the prediction is obtained for all 33 modes. Dual-tree complex wavelet (DTCWT)-based partition-prediction algorithm output is able to reconstruct all features as compared with DWT-based algorithm. Thus, the proposed partition-prediction algorithm is able to retrieve all the required features during decomposition and increases limited redundancies in the DTCWT coefficients, thus enhancing the coding efficiency in HEVC.
