Embodiment Construction

[0029] The specific implementation of the embodiments of the present invention is further described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] figure 1 This is an application scenario diagram of the file detection method provided according to the embodiment of the present application. like figure 1 As shown, the text detection method is applied to a text detection system. The text detection system may include a server 101 and a terminal 102 . The server 101 and the terminal 102 are connected through a network. The terminal 102 acquires the text image to be detected, and sends the text image to be detected to the server 101 through a network connection. After receiving the text image to be detected, the server 101 performs feature extraction and segmentation on the text image to be detected, and obtains the text image to be detected. The text area threshold map and text area center point probability map of the tex...

Abstract

The embodiment of the invention provides a text detection method and device, electronic equipment and a computer storage medium, and the method comprises the steps: carrying out the feature extractionand segmentation of a to-be-detected text image, and obtaining a text region threshold graph and a text region central point probability graph of the to-be-detected text image; obtaining a text areaframe binary image corresponding to the text area threshold image and a text area center point binary image corresponding to the text area center point probability image; and carrying out connected domain detection on the text area center point binary image, determining a clustering center of the text area, and further determining a text detection result in the to-be-detected text image accordingto the similarity between pixel points of a text area frame in the text area frame binary image and the clustering center. Through the method of the invention, the speed of text detection, especiallydense text detection, is increased.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technologies, and in particular, to a file detection method, apparatus, electronic device, and computer storage medium. Background technique [0002] Text detection is a technique for detecting text regions in images and marking their bounding boxes. Text detection has a wide range of applications and is a pre-step for many computer vision tasks, such as image search, text recognition, identity authentication, and visual navigation. [0003] The main purpose of text detection is to locate the position of text lines or characters in an image. Currently, a popular text detection method is a text detection method based on a sliding window. Based on the idea of ​​general target detection, this method sets a large number of anchor boxes with different aspect ratios and sizes, and uses these anchor boxes as sliding windows to obtain feature maps obtained by convolution operations on t...
