The frequency histogram (frequency histogram) is also known as the frequency distribution histogram. A graph representing the frequency distribution in statistics. In a Cartesian coordi

following rules: Here, U is the frequency field variable, X is the gray value, and f (x) is the statistic corresponding to the gray value. After the histogram is transformed by DCT, the spectrum image is obtained. According to the original idea, filtering out the high-frequency part can smooth the waveform. Low-pass Assume that an ideal low-pass

. When Y is a matrix.Execution Instructions:>> Y = [1,2.5,2.1;3,3.5,6];>> hist (Y)Note that Y is a matrix:1.0000 2.5000 2.10003.0000 3.5000 6.0000Y has three columns of elements, and column-wise elements produce corresponding histograms. GetObserving this graph and the matrix y, because the element of Y is maximum 1 and the minimum is 6, the interval [1,6] is divided into 0.5 intervals as 10 equal-length sub-ranges as 10 containers to accommodate the data. The square bars in the figure are three
