EdgeDetect[image] finds edges in image and returns the result as a binary image. EdgeDetect[image, r] finds edges at the scale of the specified pixel range r. ...

ImageLines[image] finds line segments in image and returns the coordinates of their endpoints. ImageLines[image, t] uses the threshold t for selecting image lines. ...

Using a variety of state-of-the-art methods, Mathematica provides immediate functions for detecting and extracting features in images and other arrays of data. Mathematica ...

MorphologicalPerimeter[image] picks out the morphological perimeter of regions of foreground in image. MorphologicalPerimeter[image, t] treats values above t as foreground.

RangeFilter[image, r] filters image by replacing every pixel by the difference of the maximum and minimum in its range-r neighborhood. RangeFilter[data, r] applies a range ...

CornerFilter[image] computes a measure for the presence of a corner for each pixel in image and returns the result as an intensity image. CornerFilter[image, r] detects ...

CurrentImage[] returns the current image captured from a connected camera. CurrentImage[n] returns n sequential image frames as a list.

CrossingDetect[image] gives a binary image in which white pixels correspond to the zero crossings in image. CrossingDetect[image, delta] treats values in image that are ...

FindFaces[image] attempts to find human faces in image and returns a list of bounding boxes. FindFaces[image, {min, max}] finds faces whose approximate pixel widths range ...

ImageCorrespondingPoints[image_1, image_2] finds a set of matching interest points in image_1 and image_2 and returns their pixel coordinates.
