mmdChickparts
Classify chicken parts in breast, legs+tights and wings

The input image is read.

Image a = mmReadgray("chickparts.tif");
mmShow(a);

a

Convert to binary objects by thresholding and then labeling the objects.

Image b = mmThreshad(a, 100);
mmShow(b);
Image c = mmLabel(b);
mmLblshow(c, "border");

b	c

Measure the area o each object and put this value as the pixel object value. For displaying purpose, overlay the background as red in the right image below.

Image d = mmBlob(c, "area");
mmShow(d);
mmShow(d, mmThreshad(d, 0, 0));

d	d, mmThreshad(d, 0, 0)

The wings are detected by finding objects with area 100 and 2500 pixels. The tights are selected as connected objects with area between 2500 and 5500 pixels.

Image wings = mmThreshad(d, 100, 2500);
mmShow(wings);
Image tights = mmThreshad(d, 2500, 5500);
mmShow(tights);

wings	tights

The legs+tights have area larger than 5500 and smaller than 8500 pixels and the breast is the largest connected object with area larger than 8500 pixels

Image legs = mmThreshad(d, 5500, 8500);
mmShow(legs);
Image breast = mmThreshad(d, 8500);
mmShow(breast);

legs	breast

Overlay the contour of the detected parts over the original image

wings  = mmGradm(wings);
tights = mmGradm(tights); 
legs   = mmGradm(legs);
breast = mmGradm(breast);
mmShow(a, wings, tights, legs, breast);

a, wings, tights, legs, breast
