The inertia measuring unit is configured to measure forces acting on the image sensor and the orientation of the image sensor. The processor is configured to receive the image data from the image sensor and process the force and orientation of the image sensor so as to determine a tilt of the image sensor. The processor is further configured to process the image data based on at least the tilt of the at least one image sensor so as to generate a corrected image data, wherein the corrected image data does not include the tilt.

Systems and methods for recognition of unreadable characters on printed circuit boards. In some embodiments, a method for recognizing characters can be utilized for recognition of damaged characters on a printed circuit board. The method can include obtaining a digital image for each of a plurality of characters on the printed circuit board. The method can further include dividing each digital image into an array of regions. The method can further include generating a data structure from the arrays of the digital images. The data structure can include gradient features based on stroke shapes on small distances, structural features based on stroke trajectories on extended distances, and concavity features based on stroke relationships.

Provided is an ophthalmic diagnosis support apparatus which enables an operator to easily acquire a tomographic image suitable for detailed observation of a candidate lesion without spending time and effort to search for the candidate lesion. The ophthalmic diagnosis support apparatus includes an acquiring unit for acquiring a wide-range image of a fundus, a candidate lesion detection unit for detecting the candidate lesion on the fundus by analyzing the wide-range image, a calculating unit for determining a degree of abnormality of the candidate lesion based on a result of the detection of the candidate lesion, and an acquiring position setting unit for setting an acquiring position of the tomographic image of the fundus based on the degree of abnormality of the candidate lesion.

A method of identifying, with a camera, an object in an image of a scene, by determining the distinctiveness of each of a number of attributes of an object of interest, independent of the camera viewpoint, determining the detectability of each of the attributes based on the relative orientation of a candidate object in the image of the scene, determining a camera setting for viewing the candidate object based on the distinctiveness of an attribute, so as to increase the detectability of the attribute, and capturing an image of the candidate object with the camera setting to determine the confidence that the candidate object is the object of interest.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, to generate a scannable document. In one aspect, a method includes receiving a scan request, wherein the scan request includes a plurality of text images; for each text image of the plurality of text images: rectifying the text image to generate a text image with parallel image lines, generating a plurality of word bounding boxes that enclose one or more connected components in the text image, wherein each word bounding box is associated with a respective word, and generating, for each respective word in the text image, a plurality of points that represent the respective word; combining the plurality of text images to form a single text document; and providing the combined image as a scannable document.

A system and a method are presented, configured for use in data display. The method comprising: providing data about vision requirement of a user, providing data about content to be displayed to the user and generating and displaying initial display data on a display device, and identifying a region of interest of the user within the display data. The method further comprising processing the display data in accordance with the data about vision requirements of the user for generating refreshed and modified display data comprising suitable image processing for at least a portion of the display data within the region of interest and transmitting the refreshed display data to be displayed on the display device. The refreshed and corrected display data thus provides improved image display to the user within the region of interest.

An image processing apparatus, an image processing system, a vehicle, an imaging apparatus and an image processing method for dynamically determining an image processing area in a captured image of vehicle's surrounding area are provided. The image processing apparatus, mounted on the vehicle, includes a processor configured to determine an image processing area on a captured image of a traveling path The processor is configured to perform processing to determine at least a part of an approximate line corresponding to a distal end of the traveling path in the captured image based on at least one of the luminance information and the color information of the captured image and processing to determine the image processing area based on a position previously determined relative to at least a part of the approximate line.

By tracking a user's eyes, an indicia scanning system can make educated guesses as to what the user is interested in. This insight could be useful in dynamically configuring a camera system, configuring an indicia decoding process or even as a method to select data that the user is interested in.
