How to work with Minimum filter

How to work with Maximum filter

97) How to work with Maximum filter.

Are useful for modifying masks. The Maximum filter has the effect of applying a choke—spreading out white areas and choking in black areas.

Step 1

Select the area to work with Maximum filter.

Step 2

As does the Median filter, the Maximum filters look at individual pixels in a selection. Within a specified radius, the Maximum filters replace the current pixel’s brightness value with the greatest or least brightness value of the surrounding pixels.

Step 3

After applying the Maximum filter.

Are useful for modifying masks. The Minimum filter has the effect of applying a spread—spreading out black areas and shrinking white areas.

Step 1

Select the area to work with Minimum filter.

Step 2

As does the Median filter, Minimum filters look at individual pixels in a selection. Within a specified radius, the Minimum filters replace the current pixel’s brightness value with the greatest or least brightness value of the surrounding pixels.

Step 3

Retains edge details in the specified radius where sharp color transitions occur and suppresses the rest of the image (A radius of 0.1 pixel keeps only edge pixels.) The filter removes low-frequency detail in an image, and has the opposite effect of the Gaussian Blur filter.

Step 1

Select the area to work with High Pass filter.

Step 2

In High Pass, you can adjust the Radius(A radius of 0.1 pixel keeps only edge pixels.)

Step 3

After applying the High Pass filter.

94) How to work with Custom.

Lets you design your own filter effect.

Step 1

Select the area to work with Custom filter.

Step 2

With the Custom filter, you can change the brightness values of each pixel in the image according to a predefined mathematical operation known as convolution. Each pixel is reassigned a value based on the values of surrounding pixels. This operation is similar to the Add and Subtract calculations for channels.

Step 3

After applying the Custom filter.
