“…Perhaps one of the most interesting recent extensions of BTC is in the area of binary pattern image coding [10] whereby the BTC bit plane is extended so that only certain patterns in each block are encoded. An excellent example of this approach is Visual Pattern Coding [32] which can preserve local gradient in each image block.…”

“…In order to illustrate how BTC works, we will let the sample mean of the block be the threshold; a "1" would then indicate if an original pixel value is above this threshold, and "0" if it is below. Since BTC produces a bitmap to represent a block, it is classified as a binary pattern image coding method [10]. The thresholding process makes it possible to reproduce a sharp edge with high fidelity, taking advantage of the human visual system's capability to perform local spatial integration and mask errors.…”
