Abstract

This paper intends to reduce the power dissipation of the GICam image compressor for capsule endoscope or swallowable imaging capsules while the gastrointestinal images are cardinal. In order to further extend the battery life of capsule endoscope, we firstly attempt to analyze the energy distribution and variation of DC/AC coefficients in 2D-DCT domain for twelve tested GI images. According to the analysis results, we can efficiently take advantages of the subsample technique to reduce the memory requirements of green and blue components and hence propose an improved ultra-low-power subsample-based GICam image compressor, called SGICam, to reduce the power dissipation of compression process. Simulation results have been shown that the SGICam image compressor can significantly save 38.5% power dissipation than GICam image one and the average PSNR is 32.18 dB, while the compression ratio can be as low as 4:1.
