read_image (Image, 'ET.png')
decompose3 (Image, Image1, Image2, Image3)
trans_from_rgb(Image1, Image2, Image3, ImageResult1, ImageResult2, ImageResult3, 'hsv')
dev_get_window (WindowHandle)
draw_rectangle1 (WindowHandle, Row1, Column1, Row2, Column2)
gen_rectangle1 (Rectangle, Row1, Column1, Row2, Column2)
reduce_domain (ImageResult3, Rectangle, ImageReduced)
threshold(ImageReduced, Region, 180, 255)
