Patent number: 9699453Abstract: Embodiments of a method and apparatus for video enhancement are generally described herein. In some embodiments, the method includes accessing a first frame of the video. The first frame can include pixel data with intensity values within one of a number of non-overlapping ranges of intensity values. The method can further include compressing the intensity values of the first pixel data to generate non-linearly compressed (NLC) pixel data such that the intensity values are compressed into smaller ranges of intensity values. The method can further include upsampling the NLC pixel data based on an upsampling ratio. The method can further include decompressing the intensity values of the upsampled pixel data by reassigning intensity values of the upsampled pixel data to intensity values in the original intensity value ranges. Other example methods, systems, and apparatuses are described.Type: GrantFiled: July 25, 2014Date of Patent: July 4, 2017Assignee: Raytheon CompanyInventors: Vernon R. Goodman, Rebekah Montgomery

Patent number: 8994818Abstract: A method includes receiving image data obtained by a laser imaging system. The method also includes identifying a minimum post spacing obtainable in a three-dimensional image constructed using the image data. The minimum post spacing defines a maximum obtainable resolution of the image.

Patent number: 8344944Abstract: A System and Method for CW interference suppression in pulsed signal processing having a front-end, an A/D converter, a data store, and a suppressor module coupled to both the A/D converter and the data store. The front-end is operable to receive a waveform and communicate such to the A/D converter to digitize for processing by the suppressor module. The suppressor module being operable to further process the digitized waveform by way of applying a FFT to obtain a corresponding amplitude spectrum of the digitized waveform, clipping the amplitude spectrum to obtain a clipped amplitude spectrum, performing successive piece-wise IFFTs on the positive frequency points of the clipped amplitude spectrum to obtain multiple amplitude-time series, each having a frequency value assigned, and then stacking such amplitude-time series successively in the data store to form a time-frequency spectrogram array to thereby facilitate suppression of interference signals and detection of data pulses.Type: GrantFiled: August 2, 2010Date of Patent: January 1, 2013Assignee: Raytheon CompanyInventor: Vernon R Goodman
