Abstract

The scalable video coding is an attractive video coding technique, due to its capability of decoding video at required resolution or required quality or required frame rate from partial bit-stream. The motion compensated temporal filtering (MCTF) is a technique used to apply discrete wavelet transform (DWT) along the motion trajectory in a video. The MCTF can be applied in two different stages (i.e. Spatial-Domain MCTF and In-Band MCTF). The IBMCTF framework supports all types of scalabilities but its complexity due to wavelet domain motion estimation is the current hurdle. Hence it cannot be used in real time video coding. This paper discusses basic concepts, the progress till date and future directions of MCTF. Experimental results of our research reveal the advantages of using MCTF and its support for scalable video coding.
