Coal and rock recognition method based on low frequency component characteristics of discrete cosine transform and learning vector quantizatio
To solve problems of small application scope and low recognition accuracy rate of existing coal and rock recognition methods, discrete cosine transform (DCT) is used to process coal and rock image blocks. DCT transform coefficients of each image block are arranged in the form of “Z” shape to express...
