Problems solved by technology

At present, the Gaussian blur effect processing of pictures on the IOS system is realized by the reliable and convenient mechanism officially provided by Apple; and due to the open source nature of the Android system, various versions are severely fragmented and the manufacturers of smart mobile terminals are not interested in the Android system. The customized design makes it impossible to directly use the official Gaussian blur algorithm provided by Android to achieve Gaussian blur effect processing on pictures

Abstract

The invention provides a method and a device for Gaussian blurring of a picture under an Android system. The method includes the following steps: selecting a picture area needing Gaussian blurring from an original picture; creating a temporary picture for the selected picture area and putting the temporary picture on a canvas; determining the radius of Gaussian blurring, acquiring the version number of the Android system, and carrying out Gaussian blurring on the temporary picture using a Gaussian blurring algorithm provided by the official Android when the version number is greater than or equal to a preset value or using a Gaussian blurring algorithm provided by the open source non-official Android when the version number is smaller than the preset value; and putting the temporary picture after Gaussian blurring on the selected picture area of the original picture.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for performing Gaussian blur processing on images under an Android system. Background technique [0002] With the development of the Internet and corresponding smart mobile terminals, the mainstream operating systems used on smart mobile terminals are the IOS system and the Android (Android) system. At present, the Gaussian blur effect processing of pictures on the IOS system is realized by a reliable and convenient mechanism officially provided by Apple; and due to the open source nature of the Android system, various versions are severely fragmented, and manufacturers of smart mobile terminals are not interested in the Android system. The customized design of Android makes it impossible to directly use the official Gaussian blur algorithm provided by Android to achieve Gaussian blur effect processing on pictures. [0003] Therefore, a new m...
