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. The term image registration is most commonly used to denote the process of alignment of images , that is of transforming them to the common coordinate system. This is done by optimizing a similarity measure between the two images. A widely used measure is Mutual Information (MI). This method requires estimating joint histogram of the two images. Experiments are presented that demonstrate the approach. The technique is intensity-based rather than feature-based. As a comparative assessment the performance based on normalized mutual information and cross correlation as metric have also been presented.
-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.
Permits to negotiate of simple form (without code) some of the most utilized
combinations of keys in the forms. It suffices with freeing the component on
the form and to activate the properties desired segun the behavior that want.

I ll probably write up a short article next week outlining how the ActionScript works, so people can modify it, and work with it more easily in Flex.
You can download the component and source code here. There are some instructions in the FLA on how to use it. Note that this is not a compiled component, so it won t show up in the components panel. You will have to copy the component, and the source file into your project. If anyone really wants a compiled version, let me know and I can provide one.
As always, I d love to hear how people use it, and would appreciate it if you would post back to the comments if you make any significant modifications so that other people can benefit from them.
DirectDisk for Win2000/NT allow you to directly access physical
sectors from floppy, hard disks, logical volumes and CDRoms.

The HexEditor component is from Markus Stephany. More info in the included zip in the sources.
The objective is to set up SPI communication between VTI Technologies digital pressure sensor
component and an MCU of an application device ATMEGA16L. In this code example:
?The MCU is configured
?SCP1000-D01 is initialized and configured
?The high resolution measurement mode is activated
?Temperature and pressure information is read always when the DRDY pin is in high state
Please refer to the document "SCP1000 Product Family Specification 8260800" for further
information on SCP1000 register addressing and SPI communication. This document applies to the
SCP1000-D01.
The code for this article was written for version 1.0 of the
Active Template Library (ATL). The current version of the code
(in SieveATL) was built with Visual C++ 6.0 and the ATL provided
with that compiler. It may be slightly different than the code
shown in the article.
The directory SieveMFC contains an MFC version of a component
equivalent to the ATL version discussed in the article. It was built
with version 5 of the C++ compiler and the MFC version provided
with it.
The code discussed in the article was later adapted for Hardcore
Visual Basic, Second Edition. Comparable Visual Basic versions are
discussed in Chapter 10 of the book.
