VI. CONCLUSION:
The enhancement of thermal images is useful in quality control , problem diagnostics, research and
development. The work indicates that histogram equalization technique can’t be used for images suffering from
non-uniform illumination in their backgrounds specifically for particle analysis purposes as this process only
adds extra pixels to the light regions of the image and removes extra pixels from dark regions of the image
resulting in a high dynamic range in the output image. The image obtained after the morphology operation is
much clear than the other images,that will be helpful in problem diagnostics.FFT transform convert the domain
of the image. So,it is necessary to enhance an image so that its information can be used that the image contain.
