12402 results about "Image processing" patented technology

In imaging science, image processing is any form of signal processing for which the input is an image, such as a photograph or video frame; the output of image processing may be either an image or a set of characteristics or parameters related to the image. Most image-processing techniques involve treating the image as a two-dimensional signal and applying standard signal-processing techniques to it. Image processing usually refers to digital image processing, but optical and analog image processing also are possible. This article is about general techniques that apply to all of them. The acquisition of images is referred to as imaging. Closely related to image processing are computer graphics and computer vision. In computer graphics, images are manually made from physical models of objects, environments, and lighting, instead of being acquired from natural scenes, as in most animated movies. Computer vision, on the other hand, is often considered high-level image processing out of which a machine/computer/software intends to decipher the physical contents of an image or a sequence of images.

Dimensioning system with multipath interference mitigation

ActiveUS20160109224A1Reducing multipath distortionReduce distortionUsing optical meansMultipath interferenceLight beam
A system and method for measuring an item's dimensions using a time-of-flight dimensioning system is disclosed. The system and method mitigate multipath distortion and improve the accuracy of the measurements, especially in a mobile environment. To mitigate the multipath distortion, an imager captures an image of an item of interest. This image is processed to determine an illumination region corresponding item-of-interest's size, shape, and position. Using this information, an adjustable aperture's size, shape, and position are controlled so the light beam used in the time-of-flight analysis substantially illuminates the illumination region without first being reflected.

System and method for automatically setting image acquisition controls

A system and method use computer image processing for setting the parameters for an image acquisition device of a camera. The image parameters are set automatically by analyzing the image to be taken, and setting the controls according to the subject matter, in the same manner as an expert photographer would be able to. The system can run in a fully automatic mode choosing the best image parameters, or a "guided mode" where the user is prompted with choices where a number of alternate settings would be reasonable.

Apparatus and method for optimized compression of interlaced motion images

An interlaced image processing module and corresponding method facilitate improved processing of interlaced motion images. In one embodiment, the interlaced image processing module receives image data frames having interlaced first and second fields and produces a reference field and error field. The reference field corresponds to the still image content of the interlaced frame, whereas the error field corresponds to the motion content of the interlaced frame, particularly the motion between fields. Motion between fields is thus represented in the error field, without redundant representation of the still image content provided by the first field. Where there is little motion between fields, the error terms will be small so the predictor preserves the coding efficiency provided by any auto-correlation in the image. Further, the interlaced image processing method does not rely upon pixel group classification, and thus avoids classification errors, and the loss of coding efficiency from still image content in motion classified blocks. Finally, problems presented by relative motion between fields are avoided, as are local artifacts. Another embodiment transforms the interlaced fields into frame data having a high frequency field and a low frequency field.
