“…For image encoding and decoding, a threshold value and Huffman coding used, these methods used to compress satellite images. S. B. Dhok, et al [43] published a new method with full search based on motion estimation technique utilizing FFT that uses a circular cross-correlation approach attemptting to optimize the runtime. The correlation-based similarity metric determines the mean subtracted adjusted coefficient for correlation between the range and the domain block.…”

“…The code stream formed by this method is encoded, and the decoded video image quality formed after decoding, inverse quantization, and inverse transform at the decoding end is worse than the original image, and the decoded image quality is poor. Because the H.264 encoding effect is relatively better, in order to improve the quality of intraframe coding, this paper draws on the intra prediction method in the video coding standard H.264/AVC and improves it to some extent [10][11][12][13][14][15][16].…”

“…Normalized covariance, that is, Zero Mean Normalized Cross Correlation (ZNCC) is a method for determining the structural similarity between two blocks from the image [23]. The best matched domain block having high normalized cross correlation [24,25] value may have large average gray level difference. This difference is reduced to zero or very small value by selecting a proper fractal encoding parameters.…”
