Embodiment Construction
[0103] Such as figure 1 As shown, a kind of purple soil image segmentation extraction method based on normal distribution H threshold provided by the present invention comprises steps:
[0104] S1: Acquire the color image containing the purple soil area, and convert the color image containing the purple soil area into the image I of the HSV color space;
[0105] S2: Determine the threshold for segmenting image I, and segment image I according to the threshold for segmenting image I to obtain binary image II;
[0106] S3: Identify the boundary of binary image II to obtain binary image III;
[0107] S4: Extract the boundary of the purple soil area in the binary image III, and obtain the binary image V from which the boundary is extracted;
[0108] S5: Fill the closed area separated by the boundary in the binary image III to obtain the binary image IV;
[0109] S6: Calculating the Hadamard product of the binary image IV and the color image containing the purple soil area to ob...
