As mentioned earlier in the article, the K-means algorithm, the first step is to find the sample points of the cluster. The following are implemented in two ways, one is the normal cycle, and the other is the full vectorization calculation.Assume:X is the MXN sample matrix, each row is a sample, m represents the number of samples, n indicates the number of featur
indicates the txt name of the output result file, and eng indicates that the language file used for recognition is in English.
3. Open the result.txt file in the tesseract-ocr directory and check that the recognition result is 7542315857. There are 3 character recognition errors and the recognition rate is not very high. Is there any way to provide the recognition rate? Tesseract provides a set of training sample methods to generate the desired recog

Anti-sample is an important concept in graphics to prevent the appearance of the phenomenon of "sawtooth. Many system plotting APIs have built-in anti-sample algorithms. However, by default, they are usually disabled, and QT is no exception. Let's take a look at the code. This Code only provides the paintevent function, and you can easily replace the relevant code in the previous chapter. {
