To acquire images with a defined blur the movement of the camera and the point of time of the image exposure have to be known, which can be achieved using a shaking table.. The
The results showed that Wishart classification provides an overall accuracy of %67.17 using the lower incidence angle PolSAR image and %65.38 for the higher
We tested the proposed algorithm for a real medium-resolution L-band ALOS PolSAR data (image has size 512 x 512) from Tehran area in Iran and a sample data set of ESAR
To represent the statistical properties and integrate contextual information of the associated image data in the analysis process we used Markov random field

3.3.1 Training Data Selection: To extract training data, the existed map and segmented image are overlaid and the segments those are under the specified map's segment are
Left: Edge image computed by ACO using Canny magnitude and edge matrixes as initial pheromone and distribution matrixes.. Right: Edge image computed using
While internal evaluation demonstrate the structure of the feature space by finding the optimum clusters, external evaluation allows us to compare the image understand- ing by users
