Abstract
In this research an algorithm for detecting a specific object and tracing its movement within a depicted series is proposed . A video file of the AVI type has been used since this type comprises a group of depicted frames . The dynamic path of the required target detected has been traced . It takes the form of a walking person. At the beginning, the detecting stage involves reading the frame and analyzing the structure of the picture by using co-occurrence matrix. The features of the picture's structure are then represented in the form of a chart, followed by cutting up the picture depending on the values of the chart in distributing of colours in order to get the required detected object to be traced . The location of the object is then specified through the calculate of the area center of the target in each frame , and after that drawing its dynamic path by using Euclidean Law for area along the depicted series.
