Embodiment

[0058] Such as figure 1 As shown, it is a schematic flow chart of a method for calibrating focus and processing an image in this embodiment. Divide the transmitted image (for example, the resolution is 4K) into several small images; reduce the entire image for ordinary transmission (for example, into a 1k background image); use high-resolution (such as 4K) for the content of the focus area, A partial image with a local size such as 1024x1024 is transmitted in high-definition (focus high-definition image); while fusion requires a filtered filter band (fusion area), and automatically generates lines and shapes (edge ​​profile 1) (edge ​​profile 2) with all of Figure 1 and transmission; the method for obtaining the focus area may be: continuously calculating the focus in each segment of video of different movies by using a deep learning model. The method comprises the steps of:

[0059] Step 101: Receive an original image, analyze the original image to obtain an image size, a...

Abstract

The invention provides a method and a system for calibrating a focus and processing an image. The method comprises the following steps of: segmenting an original image according to a preset image sizeand a corresponding relationship of the image segmentation to obtain an image block of the original image; scaling the original image to obtain a scaled image as a background image; corresponding theregion where the selected focus is located to the image block of the original image, and using the edge detection method to outline the edge contour of the content of the selected focus in the imageblock of the original image so as to select the content of the selected focus; raising the clarity of the selected focus content to a predetermined clarity value; combining the image of the selected focus region and the background image to render to obtain the composite image with improved focus content definition, and playing the composite image. The invention improves the image transmission efficiency and the effect of the user viewing the image, and does not affect the user viewing experience.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a method and system for calibrating focus and processing images. Background technique [0002] Video has become one of the essential elements of modern people's life, entertainment and work, and with the improvement of living standards, people's requirements for video clarity are getting higher and higher, especially in the recent rise of virtual reality (VR) In , the requirements for video images are further improved, because the transmission of video images in virtual reality requires binocular output, so in image transmission, double-sized image output is required. For example, a 4K picture has a transmission volume of (3840*2160*4) bytes in the ordinary network transmission, which requires 32M, and the transmission of a video image with 24 frames per second requires 32M* per second. 24=759M large amount of data, and the binocular output of VR requires ...
