In a mature, woody dicot stem, the tissue between the xylem and the phloem is the

Please briefly describe the process for unsharp masking.

Dynamic programming is a “region segmentation” method

Which methods can not be used to evaluate multi-modality image registration?

In the SNAKES deformable model segmentation method, the “snake pit” refers to the snake converging towards a strong gradient/edge along the object boundary.

In the space below, program a basic skull stripping method to obtain skullstripped.png from original.png (use other information provided to help). Hint: utilize (i) a thresholding method (see thresholdeded.png) and (ii) a morphologic operation as intermediate steps. The skull has a thickness of 40 pixels.   

How can we compute the angle of the gradient of a 2D image? (choose the best answer)
