Image Action Set

This example is not available for the Lua programming language.

The following Python code uses the THRESHOLD function in the processImages action and the TO_ZERO method to convert pixel values that are below the threshold value to black pixels of all images in the imgs input table and writes the resulting images into the imgsOut output table. This code assumes that the imgs table is loaded in advance.

s.image.processImages(
    casout={'name':'imgsOut'},
    imagefunctions=[
        {'options':{
            'functiontype':'THRESHOLD',
            'type':'TO_ZERO',
            'value':80
        }}
    ],
    table={'name':'imgs'}
)

Figure 13.29 shows the original image, and Figure 13.30 shows the processed image.
