A sequence of images is usually captured to observe the change of health status in medical diagnosis. However, an image sequence taken over year usually suffers from severe deformation, making it time-consuming for physicians to match corresponding patterns. In this paper, we propose a coarse-to-fine pipeline for retinal image registration based on convolutional neural network. By leveraging the three components of the pipeline: feature matching, outlier rejection, and local registration, we recover the deformation and accurately align multi-temporal image sequences. Experimental results show that the proposed network is robust to severe deformation as well as illumination and contrast variations. With the proposed registration pipeline, the change of image patterns over time can be identified through visual analysis.

A 0.5-V differential BPSK (D-BPSK) receiver (RX) realized in 0.18-μm CMOS is presented in this paper. This RX adopts the injection-locking technique to demodulate the received signal. The core of this RX is an injection-locked oscillator which converts the input phase transition to envelope variation for demodulation. This work is fabricated in TSMC 0.18-μm CMOS technology. The proposed RX consumes 0.97 mW from a 0.5-V supply. The sensitivity is −45 dBm. At 10-Mbps data rate, the energy efficiency is 97 pJ/b.

In this paper, a hardware design of an H.264/SVC video decoder is presented. Large size inter-coded pictures in a high frame rate require a high external memory bandwidth in decoding process. Inter-layer predictions of SVC further increase data transfer from or to an external memory. A cache-based motion compensation to sufficiently reduce overhead cycles for external SDRAM access and the bandwidth requirement is proposed. Much variation of macroblock processing cycles for CABAC decoding is another obstacle to design a SVC video decoder with macroblock based pipelining scheme. A frame level delaying method is proposed to remove the cycle variations, so that the decoder works with a steady throughput. The proposed SVC decoder shows HD1080p 60fps of decoding capability operating at 166.7MHz.
