Bachelors Academic Projects

1. Film Grain in Video Compression
Brief: Designed a guided filter assisted de-noising filter to handle film grain in videos. Quantization matrices for the x265 HEVC encoder were modeled with respect to the statistical properties of the video content.

2. Comparative Performance Evaluation of Transform coding in Image Pre-processing
Brief: Comparative evaluation of Compressed sensing, Integer wavelet transform and Singular value decomposition which could be used at the transmitter-end in order to ease the transmission and reconstruction of the images. Investigated the performance, necessary conditions, properties and time-complexity.
