Latest Patents

Miaohui Hao holds a patent for a groundbreaking invention titled "Neural-network for raw low-light image enhancement." This patent describes a neural network that receives mono-color pixels in a Bayer pattern from an image sensor. The network interpolates these pixels to generate full-color RGB pixels while simultaneously enhancing the image for better detail. The invention incorporates a Back-Projection (BP) layer added to each contracting layer in a U-net convolution neural network. This design increases feature depth as pixels are downsampled, while a BP channel shrink layer is added to each expansion layer to upsample and increase pixel resolution. The convolution layers in the BP layer are designed to lighten and darken images, generating an error that is then corrected through a weighted lightening process. The neural network learns optimal weightings to address noise and errors in the lightening process, further reducing noise through a series of convolutions and leaky Rectified Linear Units (lrelu).
