Abstract

The invention provides an interactive image segmentation method of an android system. The interactive image segmentation method is a new method for extracting image foreground objects and includes the steps that an energy function definition of a traditional image segmentation algorithm is improved, a region item is canceled, and a boundary item is enhanced, so that the influence on a segmentation result by boundary item parameters is eliminated, and the improved method is realized on an android platform; on the android platform, the setting of iterations with the highest cost performance is obtained aiming at the influence on the segmentation accuracy by the iterations of the interactive image segmentation algorithm; by means of the iteration interactive image segmentation algorithm, aiming at certain conditions of inaccurate segmentation, an interactive correction link is added to ensure the accuracy of image segmentation, and extracted scenery bodies are integrated into other background images. Due to the improvement of the interactive image segmentation algorithm, the region item of an original energy function is eliminated, so that the calculation efficiency of the algorithm is improved, the improved algorithm is applied to the android platform, and a user can segment images on android equipment easily.

Description

technical field [0001] The invention relates to an interactive image segmentation method of an Android system. Background technique [0002] Traditional image segmentation algorithms usually perform automatic segmentation. Although automatic segmentation is simple to perform, it often fails to obtain ideal segmentation results when processing complex images such as medical images. Therefore, the interactive segmentation method has gradually become a research hotspot. The interactive segmentation includes the user's operation. Compared with the automatic segmentation, it has two advantages: one is that it can accurately understand the user's requirements; the other is that the segmentation effect is better. [0003] However, interactive graph cut algorithms are all implemented on the PC platform. Due to the rapid development of mobile terminals, the demand for image processing is getting higher and higher. Currently, image editing software on the Android market, such as Meitu...
