Description: * Zooming and Shrinking Images
-(a) Write a computer program capable of zooming and shrinking an image by nearest neighbour and bilinear interpolation. The input to your program is the desired size of the resulting image in the horizontal and vertical direction. Then your program should create and display the resulting image in the desired size. Note: You cannot use the existing functions in the CImg library for zooming and shrinking.
(b) Download the image (Fig2.19(a)) of size 512 x 512 and use your program to shrink this image to sizes 256 x 256 pixels, 100 x 100 pixels, and 30 x 30 pixels, using both nearest neighbour and bilinear interpolation.
(c) Use your program to zoom each of the resulting images in (b) back to 500 x 500 with their respective interpolation methods. Explain the reasons for their differences from the original attached image. Platform: |

Description: Compute nearest neighbours (by Euclidean distance) to a set of points of interest from a set of candidate points.
The points of interest can be specified as either a matrix of points (as columns) or indices into the matrix of candidate points.
Points can be of any (within reason) dimension.
nearestneighbour can be used to search for k nearest neighbours, or neighbours within some distance (or both)
If only 1 neighbour is required for each point of interest, nearestneighbour tests to see whether it would be faster to construct the Delaunay Triangulation (delaunayn) and use dsearchn to lookup the neighbours, and if so, automatically computes the neighbours this way. This means the fastest neighbour lookup method is always used. Platform: |
