Description: -The existence of numerous imaging modalities makes it possible to present different data present in different modalities together thus forming multimodal images. Component images forming multimodal images should be aligned, or registered so that all the data, coming from the different modalities, are displayed in proper locations. Mutual Information is the similarity measure used in this case for optimizing the two images. This method requires estimating joint histogram of the two images. The fusion of images is the process of combining two or more images into a single image retaining important features from each. The Discrete Wavelet Transform (DWT) has become an attractive tool for fusing multimodal images. In this work it has been used to segment the features of the input images to produce a region map. Features of each region are calculated and a region based approach is used to fuse the images in the wavelet domain. Platform: |

Description: SPLITMERGE Segment an image using a split-and-merge algorithm.
G = SPLITMERGE(F, MINDIM, @PREDICATE) segments image F by using a
split-and-merge approach based on quadtree decomposition. MINDIM
(a positive integer power of 2) specifies the minimum dimension
of the quadtree regions (subimages) allowed. If necessary, the
program pads the input image with zeros to the nearest square
size that is an integer power of 2. This guarantees that the
algorithm used in the quadtree decomposition will be able to
split the image down to blocks of size 1-by-1. The result is
cropped back to the original size of the input image. In the
output, G, each connected region is labeled with a different
integer. - SPLITMERGE Segment an image using a split-and-merge algorithm.

Description: Abstract—The fingerprint segmentation algorithm based on gray
variance can t segment those fingerprint images with high noise.
After analyzing limitation of the fingerprint image segmentation
algorithm based on gray variance, the paper proposes the
improved algorithm to acquire the gray average and gray
variance combining to the basic gray distributing character in the
valid fingerprint image region. Experimental results indicate that
the gray average and gray variance based on the improved
algorithm are more representative of the original information of
the fingerprint image region than the gray variance based on the
classical algorithm. The segmented results of the Platform: |
