In actual data, in order to display the information in the table more intuitively, values of the same type or within a certain range are usually classified as one type, and the 'old value' is replaced by a unified 'new value ', at this time, we will use the case statement. Let's take a look at several usage cases.1. Simple case statementThe usage of a simple case statement is similar to that of switch case in C #. case capture customization. After the

According to Dr. Neal krawetz's article, the key technology used to implement this function is perceptual hash algorithm, which generates a fingerprint (string format) for the image ), the more similar the two images are, the more similar the two ima
Algorithm Overview:
First, histogram data is collected for the source image and the image to be filtered, and then the respective image histograms are normalized.
Calculate the histogram data using the babacache coefficient algorithm to obtain the image similarity value. The value ranges from 0 to 1.
0 represents extremely different, and 1 represents extremely similar (identical ).
Detailed algorithm steps:
The histogram data is generated based on th
