Light field image processing method and apparatus

The present invention provides an optical-field image processing method and apparatus. The method comprising: acquiring light field image; acquiring the light-field image marker occlusion function of each unit image, various unit images occlusion intensity variations of the light field image information and gradient information and the image according to each of the unit tag function that determines the shift amount of each image unit estimates a cost function; using the cost function, the acquired light field image of each unit of the image shift amount; and employing the image shift amount of each unit, High-resolution reconstruction of the light field. The present invention is a high resolution when the light field reconstruction, according to the optical flow can change the information light field image, acquiring light field image of each unit of the image shift amount, and using the image shift amount of each unit, to reconstruct the high resolution of the light field, which can effectively improve the spatial resolution.
