Many feature generation methods have been developed using pulse-coupled neural network. Most of these methods succeeded to achieve the invariance against object translation, rotation and scaling but could not neutralize the bright background effect and non-uniform light on the quality of the generated features. To overcome the shortcomings, the paper proposes a new method to enhance the features’ quality. The “Continuity Factor” is defined and considered as a weight factor of the current pulse… CONTINUE READING
