A convolutional neural network (CNN) method includes determining a temporary buffer layer, which is located between a first layer and a final layer of a CNN system; performing convolutional operations from the first layer to the determined temporary buffer layer of the CNN system in a first stage to generate a feature map line according to partial input data of layers before the temporary buffer layer; and performing convolutional operations from the temporary buffer layer to the final layer of the CNN system in a second stage to generate a feature map.

Convolutional neural network method and system

A local dimming system includes a light shape imitation (LSI) unit that receives a pulse-width modulation (PWM) value generated according to content of an image, the LSI unit generating luminance gain according to the PWM value; and a pixel compensation unit that performs pixel compensation on the image according to the luminance gain, thereby resulting in a compensated image. The LSI unit performs LSI computation by multiplying profile data with corresponding PWM values, and adding products of multiplication, thus resulting in a light shape.
