Problems solved by technology

This method of sequentially performing filter processing from top to bottom each time seriously affects the processing efficiency in the case of multi-filter combination, especially when the processing time of each filter is long, especially in some cases that need to be displayed in real time. In the software or application scenarios, how to make the multi-filter combination to process digital images faster and more efficiently has become the basis for realization

Embodiment

[0019] combine figure 1 As shown, a method for accelerating multi-filter combination processing of digital images is as follows:

[0020] 1) Pass in the original image and the number of filters that need to be applied.

[0021] 2) Construct a program container for loading multiple incoming filters (according to the incoming order of the filters). Among them, the filters that need parameter adjustment under a single filter are sorted at the end.

[0022] 3) Process the other filters in the container except the last filter in order, and save the processed temporary rendering.

[0023] 4) Temporary renderings Apply the last filter in the container to get the final renderings.

[0024] 5) When changing the parameters of the last filter in the container, directly replace the new filter (the last filter after changing the parameters) with the last filter in the container (mainly judge whether it is in the container by the ID of the filter) middle).

[0025] 6) Directly use the ...

Abstract

The present invention provides a method for accelerating multi-filter combined digital image processing. The unique serial numbers (IDs) of filters in each filter group are identified; the processingof a plurality of filters is accelerated by means of temporary effect pictures, so that faster and more efficient processing can be achieved after a certain filter parameter is changed or a new filteris added.

Description

technical field [0001] The invention relates to a method for accelerating multi-filter combination processing of digital images. Background technique [0002] In the process of digital image processing, it is often necessary to combine multiple filters to process the image to achieve the desired effect. The general execution process is to apply filters to the image to be processed from top to bottom according to the number and order of filters, and finally get the effect. This method reloads and processes each filter each time, so the time of each application is the sum of the processing time of each filter. Unnecessary time is spent changing filter parameter values ​​for re-image processing, resulting in reduced processing efficiency. [0003] At present, in various digital image processing platforms or application software, the number of added filters is often large. In order to achieve the final effect, the number of filters applied to an original digital image may be 1...
