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

The process 800 may further include setting weights for each of the pixel groups in the second set of pixel groups (845). Similar to as described above, the weights for each of the pixel groups in the second set of pixel groups may be based upon a table as described above with respect to FIG. 3. In other examples, the weights of each of the pixel groups in the second set of pixel groups may be automatically set to 1 because the object is included in the pixel groups. It should be recognized that other ways to determine a weight of a pixel group with the object may be used.

The process 800 may further include calculating an image luma value using, for each of the plurality of pixel groups, the weight and the pixel group luma value (850). In some examples, calculating the image luma value may include summing each of the weighted pixel group luma values, where a weighted pixel group luma value may be computed by multiplying a weight associated with a pixel group with a luma value associated with the pixel group.
