    Abstract: A method, a computer program product, and a system are disclosed to compensate for bidirectional reflectance distribution function (BRDF). The method including selecting an area of a landscape to be imaged; obtaining a plurality of aerial images of the selected area from a sensor or camera, wherein each of the plurality of aerial images comprises a plurality of pixels; combining the plurality of pixels from each of the plurality of images to form a plurality of superpixels, each of the plurality of superpixels comprising the plurality of pixels from one or more of the plurality of aerial images, and wherein each of the superpixels has a same resolution; combining the plurality of the superpixels into a single image, which simulates a satellite image; and performing a BRDF correction on one more of the obtained aerial images to adjust and/or change an intensity of the plurality of pixels.

    Abstract: A method for image processing includes obtaining a mask from an image; identifying, in the mask, a first stroke segment and a second stroke segment for possible merging; determining that the first stroke segment comprises a first plurality of cross edges that overlaps a second plurality of cross edges in the second stroke segment; identifying a plurality of cross edge pairs from the first plurality of cross edges and the second plurality of cross edges; determining a count of the plurality of cross edge pairs that satisfy a maximum width tolerance value of the first stroke segment; and merging the first stroke segment and the second stroke segment based on the count.

    Abstract: A method, a computer readable medium, and a client device are disclosed, which create multiple profiles to mitigate profiling of the client device on a network. The method includes generating a request on the client device, the request including a uniform resource locator (URL) indicating a source hosting content; forwarding the request to a profile generation application on the client device, the profile generation application configured to generate a plurality of requests for the request, and wherein only one request of the plurality of requests has system information pertaining to the client device; and sending the plurality of requests to the network to retrieve the content hosted on the source.

    Abstract: A method for image processing includes obtaining a mask of a stroke from an image and identifying a plurality of cross edges for the stroke based on the mask and a reference line. The plurality of cross edges includes a group of adjacent cross edges that intersect the reference line. The method further includes (a) calculating a first vector based on positions of at least two of the cross edges in the group, (b) expanding the group, based on the first vector, to include cross edges adjacent to the group that do not intersect the reference line, (c) calculating a second vector based on positions of at least two of the cross edges in the expanded group, and (d) expanding the expanded group, based on the second vector, to include a second group of adjacent cross edges nearby the expanded group that do not intersect the reference line.

    Abstract: A method for image processing, including: obtaining an image including a table; identifying a first line corresponding to the table in the image, a first confidence value for the first line, and a first angle for the first line; initiating a plurality of angle bins corresponding to multiple angles; calculating, based on the first confidence value, a first plurality of bin values for a first subset of the plurality of angle bins within a window surrounding the first angle; adding the first plurality of bin values to the first subset of the plurality of angle bins; identifying an angle bin of the plurality of angle bins having a maximum bin value; and rotating the image based on the angle bin having the maximum bin value.
