A marker for occluding a foreign matter in an acquired image contains a mark part whose surface is provided with a two-side continuous pattern formed by combining at least one or multiple primitives; and a fixing part which fixes a marker to a surface of foreign matter in the acquired image with the mark part to facilitate algorithm recognition and marking. The method for recognizing a foreign matter marker in an image includes the steps of performing edge detection on a planar image to acquire an edge map in the planar image; and extracting all contours in the edge map. A certain number of alternative straight-line segments are determined using an algorithm; a region is determined according to the position of each alternative straight-line segment; and finally the region of the approximate area above or below the marker is used.

An image correction device includes a line segment detection module, a shape specification module and an image correction module. The line segment detection module detects from a captured image obtained by photographing a document a plurality of line segments that correspond to the notation on the surface of the document. The shape specification module specifies shape approximation lines that approximate the surface shape of the document from the plurality of line segments. The image correction module utilizes the shape approximation lines specified by the shape specification module to correct the captured image.

A method of detecting a user interaction by an electronic device according to various embodiments may include acquiring, through a camera, a first image of a real document in which at least one first area is printed, determining whether at least one first part corresponding to the at least one first area and included in the first image is changed, and performing a function of the electronic device corresponding to the at least one first part, based on determining that the at least one first part is changed.

Provided is an image reading system that divides, with respect to image data obtained by performing a double sided reading in a state where a booklet is opened, cover sheet image data into two parts corresponding to a pair of cover sheets to arrange the two parts at a front and an end, respectively, and arranges main text image data between the front and the end, and then generates an image file from each of the arranged image data.

This image forming apparatus includes an image reading portion, an image forming portion, a feature image extraction portion, a continuousness determination portion, and an error notification portion. The feature image extraction portion extracts predetermined feature images from a plurality of respective page image data pieces. The continuousness determination portion determines whether or not each of the feature images of one or more respective target-page image data pieces satisfies a predetermined continuousness condition relative to the feature image of a previous-page image data piece. The error notification portion outputs an error notification including discontinuousness position information indicating one or both of a page-reading turn corresponding to the target-page image data piece determined not to satisfy the continuousness condition, and a turn immediately before the page-reading turn.

An image processing apparatus includes a document placing table, a scanner configured to read a reading region on the document placing table from below the document placing table, an interface configured to communicate with an image capturing device which is positioned above the document placing table to capture an image of a capturing region on the document placing table from above the document placing table, and a processor configured to generate an image file in which first image data obtained by reading a target placed on the document placing table with the scanner and second image data obtained from the image capturing device via the interface, are associated with each other, wherein the second image data is generated from at least one image of the target captured by the image capturing device from above the document placing table.

A graphic recognition-based interactive method and electronic device. The interactive method comprises: acquiring a first image to be analyzed (101); recognizing the first image to be analyzed to obtain a recognition result (102); playing a narration audio file associated with the recognition result (103); playing a question audio file associated with the interactive content of the first image to be analyzed based on the recognition result after the narration audio file is played (104); acquiring a second image to be analyzed (105); determining whether a feature graphic exists in the second image to be analyzed (106); if the feature graphic exists in the second image to be analyzed, determining whether the feature graphic overlaps with an interactive region, wherein the interactive region is an area corresponding to an answer to the question in the question audio file (108); playing a correct audio file if the feature graphic and the interactive region are overlapped (109); and playing a wrong audio file if the feature graphic and the interactive region are not overlapped (110). The said method provides increased interactivity.
