Open Operation

Using the same structural element to perform the corrosion operation on the target image first, and

then using the expansion operation is called the open operation. The open operation has the effect

of polishing the outer boundary of the image.

Close Operation

Using the same structural element to perform the expansion operation on the target image first, and

then using the corrosion operation is called the close operation. The close operation has the effect

of polishing the inner boundary of the image.

Image Binarization

The image binarization refers to the creation of binarized images that reflect the overall and local

features of images from 256 grayscale images of the brightness level via appropriate threshold

selection.

• Binarization Type: it refers to the segmentation method of binarization, including hard

threshold binarization, mean binarization, Gaussian binarization, and auto binarization. When

setting as hard threshold binarization, the grayscale is between low threshold and high threshold,

and the respective binarization image pixel is white. Otherwise, it is black. When setting as auto

binarization, you do not need to adjust other parameters, area with large grayscale in binarization is

shown as white area, and area with small grayscale in binarization is shown as black area.

• Hard Threshold Binarization:

- Low threshold: the min. threshold set by this threshold

- High threshold: the max. threshold set by this threshold.
