ABSTRACT:
A coding
and decoding process of argon plasma images using digital holography is
proposed. The digital Fourier holography is applied to two images of matrix
dimensions 512 × 512 pixels. The decoded images are improved using wiener
filtering techniques. We have constructed three basic color images of the
original image which is useful to extract the thermal distribution of the
plasma image. Also, the profiles of the reconstructed images are checked
showing better smooth profiles using wiener filter. The Mat-lab code is applied
in the operation of image processing using Fourier techniques.
