摘要

A method for computing a total weight array includes receiving an image frame captured by a content capture device and identifying a plurality of objects in the image frame. Each object of the plurality of objects corresponds to one of a plurality of pixel groups. The method also includes providing a plurality of neural networks and calculating, for each object of the plurality of objects, an object weight using a corresponding neural network of the plurality of neural networks. The method further includes computing the total weight array by summing the object weight for each of the plurality of objects.

說明書

WLA = r = 0 M - 1 c = 0 N - 1 w [ r , c ] · luma avg [ r , c ] r = 0 M - 1 c = 0 N - 1 w [ r , c ] ,
where WLA is the weighted luma average, M is a height of a pixel group, N is a width of a pixel group, w[r,c] is location r and location c in a weight array, and lumaavg[r,c] is an average luma value of a pixel at location r and location c.
