Embodiment Construction

[0043] Various details involved in the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be pointed out that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.

[0044] Such as figure 1It shows a flow chart of a text positioning and recognition method in a network animation (Flash) proposed by the present invention. This method combines the structural analysis technology of web animation with optical character recognition technology (OCR). Firstly, the method extracts the coded embedded text in the network animation, and then decomposes the network animation into several basic shapes, and the basic shapes are the main elements of the network animation. The basic shape has the characteristics of a simple background, which is more conducive to the positioning and recognition of characters by the optical char...

Abstract

The invention relates to a method for locating and recognizing letters in a network animation, which comprises the following steps: fully using a structural analysis technology for the network animation to directly extract embedded coding letters in the network animation, and decomposing the network animation into basic shapes which are main elements of the network animation; then, aiming at eachbasic shape, using a two-stage letter locating method based on inspiration, combination and feature clustering of a connected domain to locate the non-embedded letter in the basic shape, and using a noise filtration method based on a stroke width column diagram to reasonably filter non-letter connected domains, thereby locating all the non-embedded letters; using the features of a gradient columndiagram to recognize the non-embedded letters; finally, returning the recognized non-embedded letters and the embedded letters to users.

Description

technical field [0001] The invention provides a text positioning and recognition method in the network animation (Flash), which can be used in the technical fields of network animation content analysis, monitoring, retrieval and the like. Background technique [0002] With the development of computer technology and network, network animation has become a popular media form. Especially in online advertising, online animation occupies a dominant position. Subsequently, the demand for content analysis, retrieval and monitoring of network animation is becoming more and more urgent. The text in the network animation is undoubtedly an important clue to realize these demands. [0003] At present, there have been many studies on text positioning in the world. These studies can basically be divided into two categories: texture-based methods and connected domain-based methods. Texture-based methods mainly use Gabor filter, wavelet transform and other methods to calculate the textu...
