Embodiment Construction
[0097] The present invention will be described in detail in conjunction with accompanying drawing now. This figure is a simplified schematic diagram only illustrating the basic structure of the present invention in a schematic manner, so it only shows the components relevant to the present invention.
[0098] The implementation of the calculation method of the present invention is completed by writing computer programs, and the self-defined algorithms involved in the specific implementation process are described by pseudocodes. The program input is a grayscale textile image, and the program output is a collection of tiles with defects. The embodiment of the present invention includes six steps, the first three steps are the training phase, and the last three steps are the testing phase.
[0099] Described training phase comprises the following steps: Step 1: use morphological component analysis method to calculate training sample cartoon component I c , will I c Divide acco...
