A 120μW vision chip with ROI detection
نویسندگان
چکیده
A smart ultra-low power CMOS image sensor comprising an analog programmable processor array is reported. Compact and efficient motion detection algorithms are implemented to process sub-sampled images made of so-called macropixels. Only Regions of Interest (ROI) consisting of macropixels containing moving objects are read out. This drastically reduces power consumption: the 110×240 pixel image sensor fabricated in a 0.35μm technology features a power consumption of 120μW at 25fps.

Monocular Vision-Based Underwater Object Detection
In this paper, we propose an underwater object detection method using monocular vision sensors. In addition to commonly used visual features such as color and intensity, we investigate the potential of underwater object detection using light transmission information. The global contrast of various features is used to initially identify the region of interest (ROI), which is then filtered by the...

This paper is concerned with the development of a novel classifier for automatic mass detection of mammograms, based on contourlet feature extraction in conjunction with statistical and fuzzy classifiers. In this method, mammograms are segmented into regions of interest (ROI) in order to extract features including geometrical and contourlet coefficients. The extracted features benefit from...
متن کاملAdult Image Detection Combining BoVW Based on Region of Interest and Color Moments
To prevent pornography from spreading on the Internet effectively, we propose a novel method of adult image detection which combines bag-ofvisual-words (BoVW) based on region of interest (ROI) and color moments (CM). The goal of BoVW is to automatically mine the local patterns of adult contents, called visual words. The usual BoVW method clusters visual words from the patches in the whole image...
