specific Embodiment

[0139] Such as figure 1 As shown in , it is a flow chart of an embodiment of the method for detecting text regions in images of the present application. The method comprises the steps of:

[0140] Step S101: extract candidate text line region images from the target image.

[0141] Before detecting the text area in the image, it is necessary to select an image as the target image to be detected, and input it into the text area detection device in the image, and the device receives the input target image. In the present application, the target image may be various types of images, such as natural scene images, advertisement images, product images, poster images, scanned document images, and the like. The text in the target image can also be in different languages, and its text style can also be in different styles of fonts, such as conventional printing fonts or PS fancy fonts.

[0142] Since the text area detection method in the image is the basic technology of the image tex...

Abstract

The invention discloses a method and a device for detecting a text area in an image and an electronic device. The method comprises steps: a candidate text line area image is extracted from a target image; a depth study text / non text classifier through training is adopted to judge whether a sub area in the candidate text line area image is a text area, and a sub area which is judged to be the text area is marked; and sub areas marked as the text areas are combined, and a text area for the target image is acquired. The method provided by the invention can be applied to text area detection on different types of images, different languages and different styles of fonts, and the technical scheme has universality; the text line area diversity adaptability ability and the anti-noise interference ability are improved, and the detection result accuracy is ensured; and the classifier judgment areas are greatly reduced, and the detection speed is improved.

Description

technical field [0001] The present application relates to the field of image detection, in particular to a method, device and electronic equipment for detecting a text area in an image. Background technique [0002] The text information in the image is important information to understand the image content, and the text recognition of the image is the basic technology to realize the understanding of the image content. However, the premise of text recognition is to detect the text area in the image, so in order to understand the content of the image, it is first necessary to detect the text area in the image. [0003] At present, there are two commonly used text region detection methods in images. One is the text region detection method based on MSER and Adaboost classifier. The implementation process of this method is as follows: first, MSER is used to extract candidate text regions; , such as character width variance, aspect ratio of candidate text regions, etc., use the Me...
