Obesity, a prevalent global health concern, is characterized by excessive fat accumulation, which confers significant nutritional and health risks, including a shortened lifespan and diminished wellbeing. Central to the regulation of energy balance a

This article presents four modifications to the JPEG arithmetic coding (JAC) algorithm, a topic not studied well before. It then compares the compression performance of the modified JPEG with JPEG XR, the latest block-based image coding standard. We

We explore predictive coding for the JPEG baseline sequential algorithm in this article. Our objective is to reduce inter-block redundancy of discrete cosine transform (DCT) blocks. We first present an implementation of image interpolation approach a

Yamatani and Saito recently published an interesting method for predicting discrete cosine transform (DCT) coefficients of an image block, which uses partial derivatives of the image at the block boundary points. It estimates partial derivatives the

While conducting experiments with JPEG binary arithmetic coding, we noticed that if a natural photographic image is rotated by 90/spl deg/ and then coded, the DC code size is reduced in general. This led us to investigate the discrete cosine transfor

It is a well-observed characteristic that, when a discrete cosine transform block is traversed in the zigzag order, ac coefficients generally decrease in size and the runs of zero coefficients increase in length. This paper presents a minor modificat

Although it is established that the distribution of the discrete cosine transform coefficients can be modeled, it is not known how this knowledge can best be applied to improve the JPEG compression algorithms. We studied this problem by making modifi
