Abstract: A reading machine includes an image input device including a lens and a polarizer disposed over the lens, a flash and a second polarizer disposed over the flash. The image input device also includes a computing device coupled to the image input device for capturing images, the computing device, including a processor to execute instructions and a computer program product residing on a computer readable medium, the computer program product comprising instructions for causing the processor to process the captured images to recognize features in the captured images.

Abstract: Vision assistive device and user interface are disclosed. In some embodiments, a vision assistive device includes a housing having a base for positioning the housing on a surface; one or more imaging units disposed along a top portion of the housing, each imaging unit being angled downward so a central axis of the imaging unit forms an acute angle with the surface so the imaging unit captures a target image from a target object; and a control system accommodated within the housing, the control system being connected to the one or more imaging units to process the target image captured by each imaging unit and to output the target image to a user.

Abstract: A reading machine that operates in various modes includes image correction processing is described. The reading device pre-processes an image prior to optical character recognition processing by detect distortion in an image of a page by measuring an extent to which page boundaries in the image deviate from a simple rectangular shape and correcting for the optical distortion by transforming the image to restore the page to a rectangular shape.

Abstract: A reading machine has processing for detecting common text between a pair of individual images. The reading machine combines the text from the pair of images into a file or data structure if common text is detected, and determines if incomplete text phrases are present in the common text. If incomplete text phrases are present, the machine signals a user to move an image input device in a direction to capture more of the text.

Abstract: A portable reading machine detects poor image conditions for performing optical character recognition processing. The portable reading machine receives an image of sufficient resolution to distinguish lines of text but not necessarily of sufficient resolution to distinguish individual characters and processes the image to determine imaging conditions from the image. The reading machine reports imaging conditions to the user.

Abstract: A portable reading machine that operates in several modes and performs image preprocessing to prior to optical character recognition. The portable reading machine receives a low resolution image and a high resolution image of a scene and processing the low resolution image to recognize a user-initiated gesture using a gesturing item that indicates a command from the user to the reading machine and the high resolution image to recognize text in the image of the scene, according to the command from the user to the machine.
