GUI for improving resolution of lower resolution image using higher resolution image using RGB-to-HSI conversion.
Images have to be spatially co-registered.
Monochromatic (gray scale) low resolution image is converged to colored image by false color mapping to "hot" color scheme. This RGB image is then converted to Hue, Saturation and Value (HSV) image. Value component is replaced by higher resolution image and the resulting HSV image is converted back to RGB. This RGB merged image converted to gray scale is a merged image with improved spatial resolution.

To run, type:
>> resolutionmerge
Can work with any type of color or monochromatic image. If images are colored they are converted to gray scale first and then merged.
To load variables from matlab file, the file should contain variables LOWRES and HIGHRES
