Image Sequence Scene Segmentation Method for Wearable Devices

Abstract

The invention discloses a method for segmenting an image sequence scene of a wearable device. The method is mainly used for solving the problems that in the prior art, robustness is poor, and operation is complex. The method comprises the implementation steps of first, calculating the similarity coefficient between every two adjacent frames of a collected RGB color image sequence, second, calculating the quality evaluation coefficient of the RGB color image sequence, and carrying out median filtering on the quality evaluation coefficient to obtain an image quality evaluation coefficient without impactive interference, third, carrying out refinement processing on the inter-frame similarity coefficients of the image sequence by means of a quick-combination two-sided filter according to an image quality evaluation coefficient curve obtained after median filtering so that a scene boundary description curve of the RGB color image sequence can be obtained and fourth, figuring out a local maximum value point of the scene boundary description curve and making the local maximum value point serve as a scene segmentation point of the image sequence. According to the method for segmenting the image sequence scene of the wearable device, a scene change point in the image sequence can be effectively positioned, the time relation of the image sequence is reserved, and the method can be used for extracting representative images in various scenes.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to an image sequence scene segmentation method, which can be used to extract representative images in each scene and greatly reduce the data redundancy of life logs. Background technique [0002] At present, the research objects of image sequence segmentation methods are mainly concentrated in common applications, but there are few studies on image applications in wearable devices. At the same time, the application of wearable devices is in the ascendant, and there is a lot of room for development in different fields. [0003] A wearable device is a portable device that is worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not only a hardware device, but also achieve powerful functions through software support, data interaction, and cloud interaction. Wearable devices will bring great changes to people's lives a...
