In multimedia applications where images are extremely used, rate control method has significant role in image encoder performance, computational complexity and hardware implementation. We propose a simple rate control algorithm suitable for hardware implementation of JPEG2000 encoder with less computational complexity and area. The proposed algorithm which(More)
Delivering wide-angle and high-resolution spherical panoramic video content entails a high streaming bitrate. This imposes challenges when panorama clips are consumed in virtual reality (VR) head-mounted displays (HMD). The reason is that the HMDs typically require high spatial and temporal fidelity contents and strict low-latency in order to guarantee the(More)
Color gamut scalability refers to coding a video in a layered manner where the base and enhancement layers are coded in different color gamut spaces. Color gamut scalability and its relationship with spatial scalability are currently being studied for the scalable extension of HEVC (SHVC) to enable coding of ultra-high definition content having BT.2020(More)
