Japanese Patent JP2944773
Kind Code:
B2
Abstract:
PURPOSE:To assign a boundary region between a reaped region and an unreaped region to either region by picking up a color image over a reaped field and an unreaped field and applying a specific process to the image data. CONSTITUTION:A color image is picked up over a reaped field and an unreaped field to obtain an image plane. Sample regions Ma and Ka are extracted from the unreaped region M and the reaped region K on the image plate and sampling signal values of the color components of three primary colors (R, G, B) are measured on each sample region. The sampling signal values are digitized to classify the whole image data of the image plane into reaped region K, unreaped region M and the other region C. A neural network is constructed by using the sampling signal values of the color components of three primary colors (R, G, B) as the learning data. Image data corresponding to a heterogeneous region D having the digitized threshold level falling out of a prescribed range are removed from the region C and the remaining image data are classified into the reaped region and the unreaped region.
