Abstract :
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.
