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

In some examples, the method may further include identifying a direction that a user is looking, determining a location on the image that corresponds to the direction the user is looking, and determining a distance that the object is located from the location. In some examples, the weights for each of the pixel groups in the first set of pixel groups may be based upon the additional information. The weights for each of the pixel groups in the first set of pixel groups can be based upon second additional information that is different than the second additional information.

For another example, a method may include receiving an image captured by a content capture device. In some examples, the image may include a plurality of pixels. The method may further include identifying a target luma value for the image. In some examples, the target luma value may be based upon a field of view. The method may further include identifying an object in the image, identifying one or more attributes of the object, and calculating a weight for the object using a neural network. In some examples, the neural network may use the one or more attributes as input. In such examples, an attribute of the one or more attributes of the object may include an object priority, an object distance, or an object size. In some examples, the neural network may be a multilayer perceptron. The method may further include dividing the plurality of pixels of the image into a plurality of pixel groups. In some examples, each pixel group of the plurality of pixel groups may be the same size.
