In order to localize the face in an image, our approach consists to approximate the face oval shape with an ellipse and to compute coordinates of the center of the ellipse. For this purpose, we explore a new version of the Hough transformation : the Fuzzy Generalized Hough transformation. To reduce the computation time, we present also a parallel implementation of the algorithm on 2 Digital Signal...
A high-speed analog VLSI image acquisition and pre-processing system has been designed and fabricated in a 0.35 ??m standard CMOS process. The chip features a massively parallel architecture enabling the computation of programmable low-level image processing in each pixel. Extraction of spatial gradients and convolutions such as Sobel or Laplacian filters are implemented on the circuit. For this purpose,...
