As the demand for more data storage space continues to grow at an unprecedented pace, the need for real time data compression systems becomes more prominent. One of the well-known methods among lossless data compression algorithms is LZW. In this paper, a new prediction algorithm has been introduced that is able to predict whether or not a data block is(More)
Lagrange multiplier selection that is widely used in mode decision has a significant effect on the quality performance of video encoding. It has been shown in the literature that the Lagrange multiplier is closely related to the quantization factor. However, changing the Lagrange multiplier based on quantization, as it has been the case in several(More)
