Patent number: 10931891Abstract: A spectrometer includes a spectrogram, digital camera and signal processing to compensate for limits of system spatial resolution, spatial distortions and lack of precision spatial registration, limited dynamic range, The spectrogram is captured by a digital camera, and the corresponding image is converted to a wavelength and magnitude with mitigation of optical point spread function and potential magnitude clipping due to over-exposure. The clipped portions of the signal are reconstructed using tangential adjacent point spread functions as a reference or adjacent channel ratios as reference. Multichannel camera detectors having unique response magnitude ratios per wavelength are exploited to make associated direct mappings, thereby making improvements in wavelength resolution and accuracy to up to at least one to two orders of magnitude.Type: GrantFiled: August 12, 2017Date of Patent: February 23, 2021Assignee: YES WAY INTELLECTUAL HOLDINGS, LLCInventor: Kevin M.

Patent number: 9392267Abstract: Embodiments of the invention include a system and method to generate a quality rating prediction, such as MOS, of a video under test without using a second video as a reference. Instead of using a reference video, embodiments of the invention generate a pseudo reference video from measuring local impairments of the video under test. The local impairments are then accumulated to create a difference image. The difference image is then subtracted from the video under test to create the pseudo reference, to which the video under test is compared to generate the quality prediction rating. In some embodiments the local impairments may be measured by separating high frequency noise from the video under test from the video itself. Once separated, the noise is then measured and bandwidth compensated to generate the measured local impairments.Type: GrantFiled: December 15, 2010Date of Patent: July 12, 2016Assignee: TEKTRONIX, INC.Inventor: Kevin M.

Patent number: 9336596Abstract: Embodiments of the invention include a system and methods for measuring disparity and mismatch of stereoscopic images of three-dimensional video, which may indicate a level of discomfort on the part of the viewer. Measuring these parameters may also be used to give an indication that certain processes have or have not adversely effected perceived depth (i.e. through conversion from disparity to depth given a display size and viewing distance), verify camera setup or 2-dimension to 3-dimension synthesizing processes. Generating the indications and other data about the stereoscopic images uses techniques that allow processing with much less computing resources than was possible in previous systems.Type: GrantFiled: January 11, 2011Date of Patent: May 10, 2016Assignee: TEKTRONIX, INC.Inventor: Kevin M.

Patent number: 9055279Abstract: Embodiments of the invention include a system for providing a natural language objective assessment of relative color quality between a reference and a source image. The system may include a color converter that receives a difference measurement between the reference image and source image and determines a color attribute change based on the difference measurement. The color attributes may include hue shift, saturation changes, and color variation, for instance. Additionally, a magnitude index facility determines a magnitude of the determined color attribute change. Further, a natural language selector maps the color attribute change and the magnitude of the change to natural language and generates a report of the color attribute change and the magnitude of the color attribute change. The output can then be communicated to a user in either text or audio form, or in both text and audio forms.Type: GrantFiled: April 15, 2011Date of Patent: June 9, 2015Assignee: TEKTRONIX, INC.Inventor: Kevin M.

Patent number: 9013502Abstract: A method for viewing a simulated light output generated for a first display on a second display includes a variety of steps. First, the simulated light output is generated based on qualities of the first display. Next, the simulated light output is compensated for color differences, temporal differences, luminance differences including gamma difference, and differences in viewing environment between the first and the second display, in real-time. Then, the simulated light output that has been compensated for the differences and for viewing environment is output for the second display.Type: GrantFiled: December 29, 2011Date of Patent: April 21, 2015Assignee: Tektronix, Inc.Inventor: Kevin M.

Patent number: 8963998Abstract: A method of generating a predictive picture quality rating makes a disparity measurement of a three-dimensional image by comparing left and right sub-components of the three-dimensional image. Then the left and right sub-components of the three-dimensional image are combined (fused) into a two-dimensional image, using data from the disparity measurement for the combination. A predictive quality measurement is then generated based on the two-dimensional image, and further including quality information about the comparison of the original three-dimensional image.Type: GrantFiled: April 15, 2011Date of Patent: February 24, 2015Assignee: Tektronix, Inc.Inventor: Kevin M.

Patent number: 8917932Abstract: Disclosed is a processor for predicting perceptual differences between colors recalled from memory and directly viewed colors in a tested video. The processor includes a memory effects processor structured to generate compensation factors for distortions of color due to memory effects and apply the compensation factors to data from the reference video or data from the tested video. The compensation factors may include factors for changes in saturation over time, changes in hue angle, changes in uncertainty, and a categorization factor that reflects a trend in shifts and towards cardinal color centroids over time in memory.Type: GrantFiled: December 29, 2011Date of Patent: December 23, 2014Assignee: Tektronix, Inc.Inventor: Kevin M.

Patent number: 8781222Abstract: Embodiments of the invention include systems and methods for automatically detecting persons and/or other objects in a video signal. Automatic color compensation is applied to the video signal based on measured color of a reference area of the video signal. Generally the reference area is an area of the video signal that does not change often over time. The color compensated video signal is then analyzed for the appearance of objects and persons. In some instances the persons are identified using facial or other type of recognition. Counters or other trackers may provide real-time information, such as how many people are currently on a particular floor of a building.Type: GrantFiled: December 10, 2009Date of Patent: July 15, 2014Assignee: Tektronix, Inc.Inventor: Kevin M.

Patent number: 8768020Abstract: Embodiments of the invention include a method for detecting visual stress scenes in a video. First, a video that includes scenes that may cause visual stress in some viewers is received. Then, a signal representing human perceptual response from scenes in the video is generated. An envelope follower is applied to the perceptual response, from which indications that the video contains visual stress scenes may be generated. The output may also be used to control a contrast limiting circuit, which modifies the original video to remove or minimize those scenes that may cause visual stress. Additionally, output from the envelope follower may be converted to a simulated EEG signal and used to verify accurate modeling by comparing the simulated EEG signal to one measured directly from a viewer watching the same video.Type: GrantFiled: December 29, 2011Date of Patent: July 1, 2014Assignee: Tektronix, Inc.Inventor: Kevin M.
