Embodiment

[0028] figure 1 It is a schematic structural diagram of an acceleration device for image and text recognition according to an embodiment. As shown in the figure, the acceleration device includes a processor 1 , a memory 2 and an image text accelerator 3 . Among them, the processor 1, the memory 2 and the image and text accelerator 3 are bidirectionally connected to each other.

[0029]The processor 1 is used to generate the execution command for the acceleration algorithm, and transmit the generated execution command to the image-text accelerator 3 to control the image-text accelerator 3 to work; at the same time, the processor 1 accesses the memory 2, acquires the image from the memory 2, and The process of executing the image text recognition algorithm includes image orientation correction, and image cropping operation is performed according to the orientation-corrected image to obtain an image containing text.

[0030] The memory 2 is used for storing pre-input image data...

Abstract

The invention discloses an image-text recognition-oriented acceleration device, comprising: a processor, a memory and an image-text accelerator. Among them, the image text accelerator includes: operation array, softmax module, normalization module, embedding module and activation module. The operation array is connected with the softmax module, normalization module, embedding module and activation module, respectively. The functions of each functional module are relatively independent and work together to complete the rapid recognition of image data. Therefore, compared with the method of using complex network results for image processing, the use of this acceleration device for image recognition can ensure accuracy. It has a faster operation speed and effectively improves the efficiency of image recognition as a whole.

Description

technical field [0001] The invention relates to the technical field of image text processing, in particular to an acceleration device for image text recognition. Background technique [0002] Intelligent perception algorithms such as deep learning enable electronic devices to have accurate perception capabilities, such as gesture recognition, speech recognition, text recognition, etc., providing more accurate perception information for device management and control. A series of new methods have also appeared for text recognition in images, and the semantic perception technology for text has also developed to a certain stage. [0003] At present, the recognition of text in an image is mainly performed by detecting and cropping the text blocks in the image, and then using a text recognition method to recognize the text blocks in the cropped part of the image. In most cases, when recognizing text blocks in images, real-time text recognition can be achieved through a simple net...
