An Analysis on Various High Efficiency Video Codec Approach for Better Compression of High Dynamic Range Videos

Backgrounds/Objectives: The main objective of this methodology is to improve the video compression process by eliminating the perceptive details that are present in the high dynamic range videos without affecting the quality parameters in terms to various contrast and brightness properties. To do so, analysis is done on different research works that are conducted before in terms of attaining the qualified video compression and decompression.

Methods/Statistical analysis: This analysis the number of compression methods in terms of high dynamic range videos. The research is conducted to find the most considerable methodology that can retrieve the qualified videos without degradation of its quality through which high dynamic range quality video can be retrieved for the users.

Findings: The various research works has been analysed and it is evaluated by using toolkits called "DivX HEVC tool, HDR Tools, Luminance HDR" with varying quality high dynamic range videos. The performance evaluation conducted were proves that the HEVC HDR Intensity Dependent Spatial Quantization (HEVC-HDR-IDSQ) provides more qualified videos while transmitting than the other methodologies. This work also proves that the HEVC HDR Intensity Dependent Spatial Quantization method provides better result than the other methodologies in terms efficient reconstruction of videos without quality degradation.

Application/Improvements: The findings of this work proves that the HDR-IDSQ provides better result than the other approaches in terms of improved quality level and low bandwidth consumption.
