Optimized picture shape feature extraction and structuring description device and method based on horizontal coordinate

Abstract

The invention discloses an optimized picture shape feature extraction and structuring description device and method based on a horizontal coordinate. According to the scheme, PAL format analog video signals are encoded through a TVP5150 and then are collected by a DM6446 chip, an algorithm processing thread in a codec engine frame is called for achieving processing of video data and extracting of picture shape features, structuring descriptions are conducted on the features, and finally a processed result is uploaded to the Internet through the Ethernet so that users can achieve retrieval. With regard to extraction of the picture shape features, when the structuring descriptions are conducted on the features, first, graying processing is needed, then binarization processing is carried out, edge processing is conducted, afterwards, all positions with effective pixels appearing are recorded into coordinate data, the data are further divided into two lines, one line is used for browsing the shape of a picture and reappearing the original shape of the picture, and the other line is used for describing the shape in a semantization mode. The optimized picture shape feature extraction and structuring description device and method can lower product cost, reduce network data flow and improve real-time performance.

Description

technical field [0001] The invention belongs to the technical field of digital image signal processing, and relates to an intelligent video analysis method and a semantic video realization technology, in particular to an image shape feature extraction and structured description method. Background technique [0002] The rapid development of the Internet has brought great changes to human production and life. In the face of massive information, various advanced retrieval technologies have been developed rapidly, which provides convenience for obtaining effective information. The birth of the concept of the Internet of Things has injected new vitality into the development of the Internet. Its goal is to connect all objects on the earth into a huge network and promote the most extensive sharing of information. However, for the information collection end of the Internet of Things system Generally speaking, there is currently no general-purpose sensor that can collect the characte...
