Text Extraction From Images
Images and videos on webs and in databases are increasing. It is a pressing task to develop effective methods to manage and retrieve these multimedia resources by their content. Text, which carries high-level semantic information, is a kind of important object that is useful for this task.When a machine generated text is printed against clean backgrounds, it can be converted to a computer reada...
متن کاملText Extraction from Images
Automatic image annotation, structuring of images, content-based information indexing and retrieval are based on the textual data present in those images. Text extraction from images is an extremely difficult and challenging job due to the variations in the text such as text scripts, style, font, size, color, alignment and orientation; and due to extrinsic factors such as low image contrast (te...
متن کاملText Extraction from Skewed Images
The extraction of text in an image is a classical problem in the computer vision. Extraction involves detection, localization, tracking, extraction, enhancement and recognition of the text from the given image. However variation of text due to difference in size, style, orientation, alignment, low image contrast and complex background make the problem of automatic text extraction extremely chal...
متن کاملFooling OCR Systems with Adversarial Text Images
We demonstrate that state-of-the-art optical character recognition (OCR) based on deep learning is vulnerable to adversarial images. Minor modifications to images of printed text, which do not change the meaning of the text to a human reader, cause the OCR system to “recognize” a different text where certain words chosen by the adversary are replaced by their semantic opposites. This completely...
متن کاملAutomated Extraction of Text from Images using Morphology Based Approach
Existing text strings play an important role in understanding a scene image. Scene images differ from document images, which are composed of text characters of various size, shape, direction, and situation along with complicated backgrounds, such as map, picture or painting, etc. Hence, the extraction of texts on scene images is a difficult as well as challenging task. Mathematical morphology b...
