DEEP LEARNING BASED WHITE BALANCE CORRECTION OF VIDEO FRAMES
A method may include calculating a color gain by applying an automatic white balance (AWB) algorithm to a video frame of a video feed, calculating an illumination color by applying a machine learning model to the video frame, transforming the illumination color into an equivalent color gain, determining that a difference between the color gain and the equivalent color gain exceeds a difference threshold, reversing an effect of the illumination color on the video frame based on the threshold being exceeded to obtain a corrected video frame, and transmitting the corrected video frame to an endpoint.
METHODS AND APPARATUS FOR MOTION-BASED VIDEO TONAL STABILIZATION
One general aspect for motion-based video tonal stabilization uses a keyframe and motion estimation techniques to determine the level of spatial correspondence between input images and the keyframe. When the level of spatial correspondence is high, tonal stabilization is performed through regression and power law tonal transformation to minimize the color differences between images caused by automatic camera parameters without a priori knowledge of the camera model. Tonal error accumulation is reduced by using long-term tonal propagation.
IMAGE PROCESSING DEVICE AND METHOD, PROGRAM, AND RECORD MEDIUM
In the combination of a wide dynamic range by combining a first image and a second image of different light exposure conditions, pixel values at which cumulative frequency proportions (B) become first and second reference values are generated as first and second index values (Sa, Lb) with regard to the first and second images, and first and second light exposure amounts (ES, EL) are controlled under first and second target conditions that the first and second index values (Sa, Lb) have predetermined relations with first and second target values (Sat, Lbt), respectively. It is possible to shorten a time taken until convergence of the light exposure amount in relation to a change of brightness of a subject.
