The objective of this paper is to develop an ultra-low-power video compression processor for capsule endoscope to lower the RF transmitter bandwidth. In applications of capsule endoscope, it is imperative to consider battery life and performance trade-offs. Applying state-of-the-art video compression techniques may significantly reduce the image bit rate by their high compression ratio, but they all...
Wyner-Ziv coding of multiview images avoids communications between source cameras. To achieve good compression performance, the decoder must relate the source and side information images. Since correlation between the two images is exploited at the bit level, it is desirable to map small Euclidean distances between coefficients into small Hamming distances between bitwise codewords. This important...
A parallel 9/7-tap wavelet (PA97) based on the lifting structure is introduced. Compared to the Cohen-Daubechies-Feauveau 9/7-tap (CDF97) wavelet adopted by JPEG2000, it results in smaller, faster hardware with exactly the same image compression performance, and is therefore an ideal alternative to CDF97.
Distant diagnostic services require the exchange of medical images and medical data in the form of specialized patient records. Given that multiple images for one patient are often used by these services, considerable demands are placed on support applications implementation, because of the processing and transmission infrastructure limitations found on isolated rural areas. This work proposes to...
