The computational results for the #1 images and #2 images are shown in Table 1. The first column in this table is for eight images selected evenly from the video and each image is segmented individually.One can see that the accuracy OI is ranged about from 62%to 77% for #1 images, while it can reach about from 82% to 93% for#2 images. This shows that the white light source for the Combi Oven is more suitable for automatic segmentation. In fact, human observation also prefers the white light source in the Combi-Oven
