Patent number: 11715314Abstract: A computer-implemented method and system for processing a document page is based on text and non-text detections in an image path. An object block is generated for each image content identified within an input page. the blocks are extracted from the input document for downstream processing. Then, the object blocks are classified based on whether the content is text or non-text. The extracted non-text objects—which are specified by their bounding boxes—are processed separately from the rest of the content. The processing is performed on the text content blocks in parallel. However, when error diffusion is employed, the error diffusion is performed sequentially on the non-text content blocks to avoid stitching artifacts between individually error diffused patches in non-text areas.Type: GrantFiled: July 7, 2020Date of Patent: August 1, 2023Assignee: XEROX CORPORATIONInventors: Xing Li, Dhevendra Alagan Palanivel, Sainarayanan Gopalakrishnan, Rajasekar Kanagasabai
