A novel markov random field mrf model is proposed for roof edge as well as step edge preserving image smoothing.
Roof edge image processing.
Piecewise smoothness constraint is imposed on these parameters rather than on the surface heights as is in traditional models for step edges.
Edge models 3 differentt edge types are observed.
All module communication and the camera communication happen over http.
Image surfaces containing roof edges are represented by piecewise continuous polynomial functions governed by a few parameters.
Some kind of spread line.
The goal of edgedetection is to localize the variations in the intensity of animage and to identify the physical phenomena whichproduce them.
Edge detection using derivatives often points that lie on an edge.
A ridge edge where the intensity change is not instantaneous but occur over a finite distance i e usually generated by the intersection of two surfaces.
Step edge transition of intensity level over 1 pixel only in ideal or few pixels on a more practical use ramp edge a slow and graduate transition roof edge a transition to a different intensity and back.
Edge detection is widely used in imageprocessing as it is a quick and easy way of extracting mostof the important features in an image.
