Due to noise interference, there are a number of isolated black dots in the image ask how such images can be processed.

Median filtering, morphological processing.

1, median filtering: median filtering is a commonly used image denoising method, which can effectively remove isolated black spots. The principle of median filtering is to sort the pixel values around each pixel, and then take the middle value as the value of the pixel, so as to achieve the effect of denoising.

2. Morphological processing: Morphological processing is a shape-based image processing method that can be used to remove isolated black spots. Commonly used morphological processing methods include erosion, expansion, open and closed operations.
