In order to gain a comprehensive understanding of the basic concepts of image edge detection and the fundamental methods used for edge detection, we need to focus on the following aspects:

1. Basic concepts of image edge detection and fundamental methods of edge detection.

2. Implementation of edge detection for the image shown in Figure 1. The edge points should be used to fit the line parameters.

3. Implementation of edge detection for the image shown in Figure 2. The edge points should be used to fit the circle parameters.

4. Implementation of edge detection for the image shown in Figure 3. The edge points should be used to fit the ellipse parameters.

5. Utilizing the method of edge point fitting to calculate the edge lengths and angles of the 4 edges shown in Figure 4.

6. Calculating the parameters of the three circles shown in Figure 5, including the center position, radius, and concentricity of each circle.

Moreover, a detailed explanation of the various techniques utilized in the above aspects should be included to ensure a comprehensive understanding of the topic.
