Problems solved by technology

At the same time, there is also an interpolation technology that is directly applied in the field of video amplification. However, due to the single algorithm, only changing the interpolation algorithm has no follow-up details to supplement and improve, resulting in the realization effect of the algorithm cannot meet the demand.
Although the reconstruction algorithm based on super-resolution can achieve the perfection of details, it cannot meet the requirements of real-time Internet TV live broadcast and other fields.

Embodiment 1

[0042] figure 1 A schematic diagram of an image enlargement method according to an embodiment of the present invention is shown.

[0043] figure 2 A flow chart of an image enlargement method according to an embodiment of the present invention is shown.

[0044] like figure 1 and figure 2 As shown, the amplification method includes:

[0045] S1, collecting the original image;

[0046] The original image refers to an image to be enlarged, which may be a frame of image collected from live video and other videos.

[0047] S2, upsampling the original image to obtain an enlarged image;

[0048] The embodiment of the present invention adopts an interpolation algorithm to upsample the original image to complete the enlargement of the original image; classically, a bicubic interpolation or bicubic interpolation algorithm can be used, and these two algorithms insert predicted pixels into the original image. Compared with other interpolation algorithms, these two interpolation a...

Embodiment 2

[0055] like image 3 As shown, Embodiment 2 of the present invention may further include the following steps S6-S7 on the basis of Embodiment 1.

[0056] S6, if the minimum value is not reached, perform filtering processing on the deconvolution image to obtain a filtered image;

[0057] When the energy function value of the deconvolved image does not reach the minimum value, it means that the deconvolved image obtained after deconvolution still has certain impurity pixels, so the impurity pixels are further filtered out through filtering. Preferably, performing filtering processing on the deconvolution image is performing filtering processing on the deconvolution image using a guided filtering algorithm. Guided filtering is used to not only supplement the details but also ensure the edge effect of the video image.

[0058] The filtering process can filter out the impurity pixels in the deconvoluted image, and in the process of realizing the present invention, the inventor fo...

Embodiment 3

[0087] The present invention also provides a video amplification method, such as Figure 11 shown, including:

[0088] S91, collecting a frame of image in the original video;

[0089] S92, using an image enlargement method to enlarge;

[0090] Specifically, the image enlargement method refers to steps S1-S7 detailed in Embodiment 1 and Embodiment 2 of the present invention to perform enlargement processing.

[0091] S93, judging whether it is the last frame image;

[0092] The setting of step S93 is to ensure that all the images in the acquired video are processed.

[0093] S94, if so, then output the image after this pixel replacement as the target video image, and combine all the target video images to obtain the enlarged video; if not, return to continue to obtain the next frame image in the video image and use the image The zoom-in method zooms in until all the images in the video image are processed to obtain the target video.

[0094] Wherein, the combination of mul...

Abstract

The invention discloses an image / video amplification method and system. The method comprises that up-sampling is carried out on a collected original image, and an amplified image is obtained; deconvolution is carried out on the amplified image to obtain a deconvolution image; whether an energy function value of the deconvolution image obtained at present reaches a minimum is determined; and if YES, the deconvolution image obtained at present serves as a target image. Thus, the amplification effect can be ensured, and the instantaneity is satisfied.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of video image processing, and in particular to an image and video enlargement method and system. Background technique [0002] Video enlargement technology is a technology that realizes video enlargement under the premise of ensuring video clarity for low-resolution videos that cannot meet viewing requirements. [0003] At present, the video enlargement technology only enlarges the image, and the image enlargement technology mainly includes the enlargement based on the interpolation and the enlargement based on the resolution reconstruction. There are many algorithms for interpolation amplification technology. But all of them are interpolated by computing their own images. The image magnification process is an image data regeneration process, which uses known pixels to estimate unknown pixels, and the image clarity obtained by different interpolation techniques is different. Therefo...
