MEDICAL IMAGE COMPRESSION: A REVIEW
Within recent years the use of medical images for diagnosis purposes has become necessity. The limitation in transmission and storage space also growing size of medical images has necessitated the need for efficient method, then image Compression is required as an efficient way to reduces irrelevant and redundancy of the image data in order to be able to store or transmits data. It also reduces...
متن کاملCMOS Image Sensor Featuring Current-Mode Focal-Plane Image Compression
The main feature of CMOS image sensors is that they allow for the introduction of processing hardware at the pixel level. Using this characteristic, it is possible to extract from the image only the desired data, thereby reducing the output data rate. The analog processing also has the advantage of enabling high-speed operation. Owing to these features, in the last few years there has been a st...
متن کاملLinearity analysis of a CMOS image sensor
In this paper, we analyze the causes of the nonlinearity of a voltage-mode CMOS image sensor, including a theoretical derivation and a numerical simulation. A prototype chip designed in a 0.18 μm 1-poly 4-metal CMOS process technology is implemented to verify this analysis. The pixel array is 160 × 80 with a pitch of 15 μm, and it contains dozens of groups of pixels that have different design p...
متن کاملNeural Monitoring With CMOS Image Sensors
Implantable image sensors have several biomedical applications due to their miniature size, light weight, and low power consumption achieved through sub-micron standard CMOS (Complementary Metal Oxide Semiconductor) technologies. The main applications are in specific cell labeling, neural activity detection, and biomedical imaging. In this paper the recent research studies on implantable CMOS i...
متن کاملA 64 × 64 CMOS Image Sensor With On-Chip Moving Object Detection and Localization
This paper presents a 64×64 CMOS image sensor with on-chip moving object detection and localization capability. Pixel-level storage elements (capacitors) enable the sensor to simultaneously output two consecutive frames, with temporal differences digitalized into binary events by a global differentiator. An on-chip, hardware-implemented, clustering-based algorithm processes events on the fly an...
