Abstract: A method for using a computing device for modifying a lower dynamic range image to a higher dynamic range image is described. According to the method, a lower dynamic range image including a plurality of pixels is analyzed by estimating a dark channel of the plurality of pixels of the lower dynamic range image. A histogram of the dark channel is analyzed by determining the brightest peak and a local minima of the histogram. Using the local minima of the histogram as a threshold for specular highlight determination, a binary mask for specular highlight determination is computed. A final mask is created by multiplying the luminance value of the lower dynamic range image with the binary mask. The final mask is then used to determine the higher dynamic range image. A system for converting a lower dynamic range image to a higher dynamic range image displays the higher dynamic range image on a higher dynamic range display.

Abstract: Systems and methods of tracking a road boundary are provided. According to one aspect, a method of tracking a road boundary may include capturing an image from a camera, identifying a pair of regions of interest (ROI) in the image on each side of a candidate boundary position, extracting a color profile from each of the ROIs, generating a weighted color difference score by comparing the color profiles and weighting a difference between the color profiles based on a color similarity between colors in the color profiles, and outputting a determination of a detected boundary based upon the weighted color difference score.

Abstract: A method for increasing the resolution of a series of low resolution frames of a low resolution video sequence to a series of high resolution frames of a high resolution video sequence includes receiving the series of low resolution frames of the video sequence. The system determines a first plurality of semantically relevant key points of a first low resolution frame of the series of low resolution frames and determines a second plurality of semantically relevant key points of a second low resolution frame of the series of low resolution frames. The system temporally processes the first plurality of key points based upon the second plurality of key points to determine a more temporally consistent set of key points for the first plurality of key points.

Abstract: Aspects of the present invention are related to methods and systems for autonomous navigation using visual-landmark recognition. One method may include scanning a captured image to detect a machine-readable marker and extracting encoded data therefrom. The data may include an identifying key usable to access a database to retrieve physical attributes associated with the marker. The method may include using the physical attributes to compute a position and an orientation of a mobile agent relative to a landmark object associated with the marker. The method may further include determining a path toward a next route location based on the position of the next route location and the computed position and orientation of the mobile agent and controlling the mobile agent to drive along the path toward the next route location.

Abstract: A method for image enhancement may include selecting a plurality of patches of an image and determining at least one dimensionally reduced feature for each of the plurality of patches. The system may further determine a generally closest cluster from a set of clusters for each of the dimensionally reduced features and select a corresponding set of regression coefficients for each of the set of generally closest cluster. The system may also apply the selected set of regression coefficients to a corresponding patch to enhance the image.
