Abstract: A computing device is configured to generate a thumbnail image. The computing device may receive a source image, downscale the source image to generate a downscaled image, process the downscaled image with a neural network to generate a non-linear thumbnail image, wherein the neural network operates according to parameters that were trained using saliency maps, and wherein the non-linear thumbnail image includes one or more non-linearly scaled salient features relative to one or more original salient features in the source image, and output the non-linear thumbnail image.

Abstract: Systems and techniques are described for image processing. For instance, an imaging system can obtain an input image with a first region and a second region, both at a first resolution. The imaging system can determine that the first region is more salient than the second region (e.g., based on a saliency map mapping saliency values to pixels of the input image). The imaging system can use a first process (e.g., using a trained network, such as of a machine learning super resolution system) to modify the first region to increase the first resolution to a second resolution. The imaging system can use a second process (e.g., based on an interpolation process) to modify the second region to increase the first resolution of the second region to the second resolution. The imaging system can generate and/or output an output image including the modified first region and the modified second region.

Abstract: According to aspects of the present disclosure, a radar transmitting power and channel performance monitoring apparatus is disclosed. In one example, such apparatus may include a plurality of couplers, power combiners of multiple stages, and a power monitoring module, wherein the couplers are connected with transmitter/receiver modules of the radar, and each coupler may be configured to collect a transmitting power of a corresponding transmitter/receiver module. Further, the power combiners may be configured to combine the transmitting power collected by each coupler and input the resultant total power to the power monitoring module, and the power monitoring module may be configured to monitor the total power. In addition, aspects of the present disclosure may test an amplitude and phase consistency of the transmitting and receiving channels of each T/R module of radar to ensure the performance of the radar system.
