Abstract
A system and method of detecting trees in an image. A system and method may receive a dimension related to the trees in an input image. A two dimensional (2D) high pass filter may be applied to the input image to produce a high pass image. Objects may be marked in the high pass image based on the dimension. A processed image may be produced by associating a set of pixels in the high pass image with a respective set of grayscale values. A density operator may be applied to the processed image to identify locations with high frequency changes. Shapes may be defined to include the locations. Trees may be identified by grouping one or more shapes.
