The Use of Sun Elevation Angle for Stereogrammetric Boreal Forest Height in Open Canopies [PDF]

open access: yes
Stereogrammetry applied to globally available high resolution spaceborne imagery (HRSI; less than 5 m spatial resolution) yields fine-scaled digital surface models (DSMs) of elevation. These DSMs may represent elevations that range from the ground to the

Traffic sign recognition using local directional histogram of oriented gradients [PDF]

open access: yes
Histogram of Oriented Gradients (HOG) describes an image gradient by calculating vertical and horizontal gradient magnitudes and directions. HOG uses a one-dimensional (1D) centered derivative mask [−1, 0, +1] for horizontal gradient and its rotations at
