Patent number: 11893747Abstract: The invention provides an image segmentation method and an electronic device. The image segmentation method includes the following steps. Regression analysis is performed on a first gray-scale image to obtain a residual image having an object backbone area. A pixel value of each pixel in the object backbone area is defined as an average gray-scale value of the object backbone area in the residual image, and a second gray-scale image having the object backbone area is generated. It is recursively determined whether a residual polarity of each adjacent pixel adjacent to edge pixels of the object backbone area in the residual image is the same as a residual polarity of the corresponding edge pixel, and whether a pixel value of each adjacent pixel is greater than a first threshold, so as to expand the object backbone area in the second gray-scale image, which is extracted as a target object.Type: GrantFiled: July 1, 2021Date of Patent: February 6, 2024Assignee: Coretronic CorporationInventor: Huai-En Wu

Patent number: 11853393Abstract: A solution to identify the layout elements in a document is provided. The documents are formulated in an integrated visual space, where they are treated uniformly as a rasterized image. The transformation to image space facilitates exploitation of a spectrum of stylistic cues, such as spacing between the lines and paragraphs. Effective recognition of layout elements is provided by applying a synthetic generator model that creates artificial documents with the required labels and bounding boxes. The generator model is based on a Bayesian Network, offers full flexibility in controlling the document types and labels, and can introduce artificial defects to synthesize low-quality documents. An artificial intelligence model for detecting layouts is trained based on these synthetic documents and the resultant model is used to identify the layout elements in real-world documents. The resulting layout elements, when augmented with the text content, greatly aids in effective information retrieval.Type: GrantFiled: December 9, 2021Date of Patent: December 26, 2023Assignee: JPMORGAN CHASE BANK, N.A.Inventors: Natraj Raman, Sameena Shah, Manuela Veloso
