The template matching is an important technique used in pattern recognition. It aims at finding a given pattern within a frame sequence. Pearson's Correlation Coefficient (PCC) is widely used to evaluate the similarity of two images. This coefficient is computed for each image pixel, which entails a computationally very expensive process. This paper proposes an implementation of the template matching...
In this work a three-phase power supply to emulate voltage disturbances that occur in an electrical network is presented. The type of disturbances that can be generated are voltage drop (voltage sags), over voltage (voltage swell). To maintain the value of the disturbance is necessary to implement a close loop with a control technique on it. Three control schemes were probed in this work: PI, PID...
