Embodiment 1

[0042]At present, the improvement of image super-resolution based on deep learning methods is usually aimed at model structure or training methods. These methods work well when super-resolution processing is performed on the second image obtained by simulation, but when processing the second image actually acquired , the effect is significantly reduced. In order to solve this technical problem, when the application trains the high-frequency image generation network and the low-frequency image generation network, the training samples used are directly selected from the real second image and the real first image collected by the terminal device to ensure the training The robustness of the resulting high-frequency image generation network and the trained low-frequency image generation network when performing super-resolution processing on real second images. In addition, when the present application trains the high-frequency image generation network and the low-frequency image ge...

Abstract

The invention is suitable for the technical field of image processing, and provides an image processing method and device, and terminal equipment. The method comprises the steps: obtaining a to-be-reconstructed image; extracting a high-frequency component and a low-frequency component of the to-be-reconstructed image to obtain a first high-frequency image composed of the high-frequency component and a first low-frequency image composed of the low-frequency component; inputting the first high-frequency image into a trained high-frequency image generation network to obtain a second high-frequency image output by the high-frequency image generation network; inputting the first low-frequency image into a trained low-frequency image generation network to obtain a second low-frequency image output by the low-frequency image generation network; and generating a reconstructed image according to the second high-frequency image and the second low-frequency image, wherein the resolution of the reconstructed image is higher than that of the to-be-reconstructed image. Through the method, an image with a better effect can be reconstructed.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to an image processing method, device, terminal equipment, and computer-readable storage medium. Background technique [0002] Image resolution refers to the sensor's ability to see or measure the smallest objects, depending on pixel size. Digital images, recorded as two-dimensional signals, always require high resolution for most applications. Over the past few decades, imaging technology has advanced rapidly and image resolution has reached a new level, but there is still a desire for better image resolution in many applications. For example, digital surveillance products often choose to sacrifice image resolution to some extent to ensure long-term stable operation of recording equipment and appropriate frame rates for dynamic scenes; a similar situation exists in the field of remote sensing: in the field of space, spectrum and image resolution The...
