boosting using DWT is proposed. A novel Hybrid Hexagonal Kite Cross Diamond Search (hybhks) algorithm is proposed. In this thesis, compression techniques involving the concepts of spatial and temporal correlation of rows are implemented where only alternate rows of the video are fed to the video encoder. Preview, pDF 2814Kb, the wide use of images and videos in the day to day communication in recent creative writing magazine trends made video compression a significant feature in information transmission and social networking. Motion Estimation (ME) is the widely used scheme in many encoders like mpeg-2, mpeg-4 and.264 that removes temporal redundancy. Based on the conclusions drawn modifications to kcds and hexs are proposed by imparting the concept of motion vector prediction. Repository Staff Only: item control page.
Thesis video compression
It has the capability of adaptive switching of search patterns based on the type of motion of the block that can reduce the computational complexity of the encoder maintaining quality. Video Compression may still be increased by reducing the information to be encoded. Ragasudha, Narapaneni (2014 efficient Video Compression Schemes. In this thesis, many ME algorithms like Full Search, Logarithmic Search, Diamond Search, Cross Diamond Search, Kite Cross Diamond Search (kcds Hexagonal Search (hexs Enhanced Hexagonal Search (enhexs) etc. Also analysis is also done on down sampling and up-sampling of video before and after encoder and decoder respectively. Analysis is done on the impartation of Discrete Hartley Transform in video encoding.
