This paper presents the first prototype of automating a low-cost printed circuit hoard (PCB) inspection on physical defects through the development of a technique for image detection using a Genetic Algorithm (CA). A GA is a powerful search technique which is applicable to various type of problems. The algorithm works on the principle of simulation of the evolution of individual structures via prwesses such as selection, mutation and crossover. This research aims to detect rotation angle and displacement of a board placed arbitrarily on a conveyor belt passing under the camera. Variant rotation and displacement values are represented as chmmosoma to create a population which will evolve using GA operators and a specially tailored fitness function. Ideal parameter tuning of CA plays an important mle in boosting the capability of this technique in order to perform effectively in the PCB inspection environment. Previous results regarding the use of CA on ARM based embedded PCB inspection system which focused on rotation and displacement of Integrated Circuits provides the motivation for this research. This research is run on Linux-based PC and real industrial samples PCB images are used in the implementation.

A novel technique for visually lossless medical image compression is presented Visually lossless compression is defined as removing visually insignificant information without evoking any degradation in image quality, through the suppression of visual distortions. An advanced perceptual distortion metric is adapted into the JPEG 2000 coding framework, whilst maintaining bit-stream compliance. Current simulation results have shown superior compression gains over that of the state of the art JPEG-LS and JPEG 2000 Lossless coders, without any visible distortions.

Standard image interpolation methods generally use a uniform interpolation filter on the entire image. To achieve a better performance on specific structures, some content adaptive interpolation methods, such as Kondo's method (1), have been introduced. However, these content adaptive methods are limited to fit image data into a linear model in each class. We investigate replacing the linear model by a flexible non-linear model, such as a feed-forward neural network. This results in a new interpolation algorithm based on known classification, but achieving better results. In this paper, such a classification-based neural network approach and its evaluation are presented. Both objective and subjective image quality results indicate that the proposed method gives an additional improvement in the interpolated image quality 1 .
