Abstract: In an embodiment, a method includes receiving a low-light digital image; generating, by at least one processor, a resulting digital image by processing the low-light digital image with an encoder-decoder neural network comprising a plurality of convolutional layers classified into a downsampling stage and an upscaling stage, and a multi-scale context aggregating block configured to aggregate multi-scale context information of the low-light digital image and employed between the downsampling stage and the upscaling stage; and outputting, by the at least one processor, the resulting digital image to an output device.

Abstract: A method for training a model, the method including: defining a primary model for identifying a class of input data based on a first characteristic of the input data; defining a secondary model for detecting a change to a second characteristic between multiple input data captured at different times; defining a forward link from an output of an intermediate layer of the secondary model to an input of an intermediate layer of the primary model; and training the primary model and the secondary model in parallel based on a training set of input data.

Abstract: Embodiments include apparatus and methods for training and/or using a convolutional neural network. An image pyramid is calculated from an original image including at least one object of interest. The image pyramid includes a first image under analysis and a second image under analysis. Image patches are calculated at a first predetermined size relative to the first image under analysis and a second plurality of image patches having a second predetermined size relative to the second image under analysis. The convolutional neural network is trained using the image patches and subsequent images are analyzed by the convolutional neural network using similar image patches.
