Discrimination method of crystal precipitation based on improved connected domain algorithm

It is difficult to distinguish whether there are precipitated crystals in the evaporating dish in the evaporation crystallization chemistry experiment of middle school via video. Firstly, this paper uses CLAHE algorithm to enhance the gray image of the original image. On this basis, an improved connected domain algorithm is proposed to enhance the roughness of crystal particle size, combined with the texture measurement algorithm of gray level co-occurrence matrix, a crystal precipitation discrimination algorithm based on connected domain roughness enhancement is proposed. The algorithm is tested on the real-time experimental video of middle school students, and the results have a high recognition rate, which verifies the effectiveness of the algorithm.
