In this paper we present a class of emergent algorithms called Marching Pixels which can be used for real time image processing in smart camera chips. Marching Pixels are based on hardware agents which are virtually crawling in a pixel grid image to find attributes like centroid, rotation and size of an arbitrary number of objects given in an image. Due to the distributed and local processing scheme...
A multi-spectral camera is introduced to make up the traditional defects in this article, which is sensitive to NIR, red and green lights. It is with three CMOS sensors to collect the lights in the three wave-lengths. Besides, an FPGA is used to serve as the control unit. The information collected is stored as BMP files into a Compact Flash™ card. The NIOS-II CPU provided by the Altera Corporation...
Small satellites have captured the imagination worldwide of satellite designer due to its exciting technological and economic possibilities. Thus, pico satellites team of research group on intelligent machines laboratory, is developing ERPSat-1, ENIS REGIM pico satellite 1, the first pico satellite of the engineering school of Sfax, Tunisia. ERPSat-1 has three basic missions such as ground station...
Edge detection operation is an essential part in the field of image processing. There are few ways to improve the performance of edge detection. This paper proposes a FPGA-based approach Sobel edge detection. An image is captured by a CMOS camera and converted into RGB color space and the image is converted into grayscale to obtain image intensity for edge detection. The proposed Sobel edge detection...
