Color edge detection with the least square numerical method

الملخص EN

The edge detection considers the important technical in the digital image processing, many edge detection operator already exist to edge detection in digital color image.

In this study we detection the edge for many real color image that represented the type of digital image by using anew operator that is into least square approximation method that one of the type of the numerical method.

We using this method to creation algorithm that depends on the local scan of the image in four major directions (the horizontal direction, the vertical directions and the major diagonal direction, and the second diagonal direction), and we using the stander detection edge Sobel operator to comparison between the result, and this work depends on the using the best threshold to detection the edge of the real images.

From the results obtained in this work, that the new method can to detection on the edge in digital color image with high efficiency compare with standard methods used to edge detection.

Also the result obtained that the suggested operator that using is very useful to detect the edge in the digital color image.
