This work presents the hardware implementation of the RLA (Richardson-Lucy Algorithm) for image restoration task, in which the images are blurred by relative motion between camera and the scene. In this case the RLA was implemented in an FPGA-based platform using the hardware description language VHDL, and assuming the absence of additive noise in the capturing image system. The overall architecture...
The quality of motion-blurred image restoration is highly dependent on the blur direction identification, which is an important and difficult problem in image restoration. In frequency domain, we summarize four important characteristics of motion-blurred image, and then propose a method to reduce the impact of deficiencies in frequency characteristics by using the binaryzation operation, the morphological...
Active contours model (snake) is a typical quantity dynamic contours model. Its main principle is to define a curve with energy in the area in which the researcher is interested, approaching the contours of the object through optimizing the energy function dynamically. Its biggest defect is that it can hardly handle the topological structure transformation when extracting the object contour. Geodesic...
