Embodiment

[0075] Embodiment: a kind of multimedia video object processing method, this method comprises the following steps:

[0076] (1) The top layer of the grammatical structure of the standard MPEG video format is the frame image group GOP (Group of picture), which is composed of three main compression types of image frames (I frame, P frame, B frame), and a GOP can be divided into There are 3 subcategories (SGOP, Sub Group of picture). When processing a video, the type of the macroblock (MB, Marco Block) of each frame in each SGOP is analyzed separately, and any MB that satisfies certain rules is considered to have changed. Comparing the number of MBs that change in each frame with the total number of MBs, the possible degree of lens change c is obtained. The closer c is to 1, the greater the probability of lens conversion. Set a certain threshold t, if c>t, it is considered that the scene has changed and segmented;

[0077] Specifically include the following steps:

Abstract

The invention discloses a multimedia video object processing method which comprises the steps as follows: (1) carrying out scene dividing on an MPEG video based on macro block information; (2) pre-reading a video needed to be jointed, obtaining various information and searching a proper joint scene; (3) searching the inlet point and the outlet point of the joint and carrying out regulation on various information of the accessed video; (4) selecting a proper audio joint point to realize audio-video seamless joint; (5) setting a video buffer area and unifying the code rate of the video to be jointed; (6) carrying out coarse extraction on a moving object in the video in a time domain; (7) carrying out watershed processing on the coarse extraction result, carrying out space region merging and leading to a accurate segmentation object. The .invention is characterized by simple and high-efficiency algorithm, low system resource consumption and fast speed and high accuracy of processing.

Description

technical field [0001] The invention relates to a multimedia video object processing method, in particular to a multimedia video video intelligent scene segmentation, seamless splicing and object extraction method. Background technique [0002] With the development of computer and network technology, the influence and effect of applications represented by media on human society have become more and more obvious, which has greatly promoted the mutual penetration and rapid development of many industries, and gradually changed the working structure of the entire human society. and lifestyle, thus, the processing of multimedia objects has also received more and more attention. [0003] The main component of multimedia information is visual information, which has the characteristics of intuitiveness and large amount of information. Visual information is an important functional means for humans to recognize the world, including still images, video and image sequences, computer gr...
