Systems and methods are provided for image scaling with enhanced compression. One embodiment is a processor that receives an instruction to scale an input image to create an output image that is higher in resolution, and analyzes rows of the input image in sections according to a run length of a predetermined number of consecutive pels. For each run length of consecutive pels, the processor determines a cluster of adjacent pels within the run length having a color intensity value within a threshold range, and determines a replacement intensity value for the cluster based on at least one color intensity value of a pel in the cluster. The processor creates the output image by: upscaling the cluster by the scale factor to multiply a number of pels in the cluster, and changing an intensity value of all pels in the cluster to the replacement intensity value.

Each iteration includes using a gradient descent (GD) approach with a learned forward operator, to generate an intermediate high-resolution multispectral (IHRMS) image with an increased spatial resolution and a smaller error to the DSRMS image compared to the stored MS image. Project the IHRMS image using a trained convolutional neural network (CNN) to obtain an estimated synthesized high-resolution multispectral (ESHRMS) image, for a first iteration. Use the ESHRMS image and the PAN image, as an input to the GD approach for following iterations. The updated IHRMS image is an input to another trained CNN for the following iterations. After predetermined number of iterations, output the fused high-spatial and high-spectral resolution MS image.

Super-resolution with reference images
10885608 · 2021-01-05 · ·

In implementations of super-resolution with reference images, a super-resolution image is generated based on reference images. Reference images are not constrained to have same or similar content as a low-resolution image being super-resolved. Texture features indicating high-frequency content are extracted into texture feature maps, and patches of texture feature maps of reference images are determined based on texture feature similarity. A content feature map indicating low-frequency content of an image is adaptively fused with a swapped texture feature map including patches of reference images with a neural network based on similarity of texture features. A user interfaces allows a user to select regions of multiple reference images to use for super-resolution. Hence, a super-resolution image can be generated with rich texture details incorporated from multiple reference images, even in the absence of reference images having similar content to an image being upscaled.
