Embodiment 1
[0069] Such as figure 1 Shown, the present invention comprises the following steps:
[0070] Step 1: Transform the color image to be repaired from RGB to HSI to obtain three component submaps of H hue, S saturation, and L illuminance;
[0071] (1) Obtain the parameters of the area to be repaired in the image: the X and Y axis coordinates of the starting position of the area to be repaired in the image, and the length and width of the area.
[0072] (2) The values of H, S, and I will be calculated through the values of the three sub-images R, G, and B of the area to be repaired, and the calculation formula is as follows:
[0073] I=1 / 3(R+G+B)
[0074] S=1-(3 / (R+G+B)) * a
[0075] H=cos^(-1)((0.5 * ((R-G)+(R-B))) / ((R-G)^2+(R-B) * (G-B))^(0.5))
[0076] Among them, a is the minimum value among R, G, and B.
[0077] Step 2: For each pixel of the area to be repaired in the H, S, and I component subimage images, perform regional feature judgment, and divide it into a fla...
