Machine learning -- evaluation of classification algorithms

Problems in classification accuracy If there is a cancer prediction system, input the patient's information to determine whether there is cancer. Is it reasonable to use only classification accuracy to evaluate the quality of the model? If the prediction accuracy of the model is 99.9%, can the model be considered good? If the probability of ca ...

OpenCV computer vision -- image threshold processing and adaptive threshold Otsu

Threshold processing refers to eliminating pixels in the image that are higher or lower than the threshold. Image threshold processing is mainly to set a threshold: greater than this number is given a value, less than a number is given another value, and the pixel value of the image is changed into the middle of two gray values to realize image ...
