2results about How to "Accurate face recognition" patented technology

An image processing apparatus and air conditioner include: an acquisition unit configured to acquire low-light and infrared images; and a processing unit comprising: a low-light image enhancement algorithm model, which includes: a gradient reconstruction module comprising: a frequency domain processing branch configured to transform the gradient map of the low-light image from the spatial domain to the frequency domain to extract the phase spectrum and amplitude spectrum; and a spatial domain processing branch configured to fuse the gradient map of the low-light image with the infrared image in the channel dimension; the gradient reconstruction module adds the residual of the spatial domain processing branch to the amplitude spectrum to obtain an enhanced amplitude spectrum; an amplitude-enhanced gradient map of the low-light image is obtained through an inverse Fourier transform between the enhanced amplitude spectrum and the original phase spectrum; and an enhanced visible light image is generated through an encoder-decoder architecture based on the gradient features of the amplitude-enhanced gradient map of the low-light image and the image features of the low-light image; this application has high accuracy and is suitable for use in smart home appliances.
