Abstract
An apparatus includes a first circuit and a second circuit. The first circuit may be configured to calculate a feature descriptor for each pixel of an image. The feature descriptor generally comprises sixteen discriminative feature values. The feature values are generally computed based on arithmetic combinations of a number of neighboring pixels at predetermined locations around each pixel. The second circuit may be configured to implement a color classification process combining multiple weak depth-two decision trees in a cascade. The second circuit may generate a plurality of likelihood values expressing a likelihood of a specific color road marking at each pixel location of the image using the feature descriptor of each pixel of the image.
