Near-sensor Image Processing, a Vlsi Realization
نویسندگان
چکیده
We present a single-chip image processing solution for industrial vision systems. A processor matrix is interleaved with a photo diode matrix. The circuit solution is well suited for both gray scale and binary operations on images. A gray scale image is obtained by using the time needed to integrate the photo-current to a certain voltage. The photo-diode read-out unit is built with a minimal set of components, and provides good matching between pixels. The power supply can be adjusted to minimize the power consumption. A number of operations, that show the computing capacity, are presented.

A VLSI sorting image sensor: global massively parallel intensity-to-time processing for low-latency adaptive vision
This paper presents a new intensity–to–time processing paradigm suitable for VLSI computational sensor implementation of global operations over sensed images. Global image quantities usually describe images with fewer data. When computed at the point of sensing, global quantities result in a low– latency performance due to the reduced data transfer requirements between an image sensor and a pro...

متن کاملPulsed Multi-Layered Image Filtering: A VLSI Implementation
Image convolution similar to the receptive fields found in mammalian visual pathways has long been used in conventional image processing in the form of Gabor masks. However, no VLSI implementation of parallel, multi-layered pulsed processing has been brought forward which would emulate this property. We present a technical realization of such a pulsed image processing scheme. The discussed IC a...
