Embodiment Construction
[0027] In view of the fact that human vision itself has the ability of color constancy, it can automatically correct the color shift in the scene, the retina has the ability to adapt to light and dark, and the characteristics of the retinal neuron receptive field, based on this, the present invention proposes a multi-light source based on the physiological mechanism of the retina Color const method. This method simulates the light-dark adaptation ability of vision and the characteristics of retinal neuron receptive fields, and establishes a model based on ON-type and OFF-type receptive fields based on the division of bright and dark areas. This model can well estimate the position and Color, and parameters can be adjusted to adapt to different scene images.
