r-θ分布を利用したパンの画像認識

抄録

A trial of “Bread recognition by the r-θ histogram ” was done and the following results are obtained．1.Changing the orientation or the location of the bread gives rise up the complicated change of the histogram. 2.When the origin of the coordinate system is taken at the center of the bread region, the histogram becomes about identical except the shift along the θ axis. 3.The shift along the θ axis will be disappear when the original histogram is shifted as the maximum histogram angle becomes to the zero.
