Optical tomography: a new filter technique for post processing image
Filtering process is important to make sure the resultant image is free from noise. This paper introduces a new filtering technique for optical tomography to reduce the noise or called a smearing effect. With this technique, it also can increase the Peak Signal to Noise Ratio (PSNR). This smearing e...

| Summary: | Filtering process is important to make
sure the resultant image is free from noise. This paper
introduces a new filtering technique for optical
tomography to reduce the noise or called a smearing
effect. With this technique, it also can increase the Peak
Signal to Noise Ratio (PSNR). This smearing effect is
resultant from Linear Back Projection (LBP) algorithm
that is applied in image reconstruction process. To solve
the smearing effect, a new technique that use a threshold
value is introduced which is called Averaging Grouping
Colour (AGC) bar. The result shows that the AGC bar
type 5 is the most suitable technique to be implemented
in this system. |
