Absolute moment block truncated coding (AMBTC) is a lossy image compression technique aiming at low computational cost, and has been widely studied. Previous studies have investigated the performance improvement of AMBTC; however, they often over describe the details of image blocks during encoding, causing an increase in bitrate. In this paper, we propose an efficient method to improve the compression ...

In this paper, we propose a novel lossless data hiding method for vector quantization (VQ) compressed images. The existing methods sort the codebook based on the intensity of codewords to obtain rearranged indices (RI). The indices in RI are predicted, and the secret bits, indicators, and prediction errors are then encoded to construct an output code stream (CS). However, the neighboring indices of ...

Due to the increasing consumption of food products and demand for food quality and safety, most food processing facilities in the United States utilize machines to automate their processes, such as cleaning, inspection and grading, packing, storing, and shipping. Machine vision technology has been a proven solution for inspection and grading of food products since the late 1980s. The remaining challenges,...
