Because of the complexity of the growth environment of the camellia fruits, the most of the images obtained by the fruit-picker" visual system are uneven illuminated. For these uneven illuminated images, the traditional image segmentation method cannot acquire good effect. Aiming at above problems, a segmentation algorithm based on luminance uniformity is proposed. This algorithm compensates the area block of different luminances in the camellia fruits' image, so that the luminance of the whole camellia fruits' image can be homogenized and t...
