Abstract The optical imaging system has many problems, such as noise. Therefore, the challenge is to design algorithms reduce or eliminate visual noise in systems. In this study, there are several steps identify and First, we determine type of Then, median smoothing, Winner, Frost, Kuan Lee applied 3x3, 5x5 7x7 sliding windows. histogram algorithm used recognize types noise, which divided into additive multiplicative image quality after smoothing evaluated using statistical criteria mean...

Image fusion is integrating multiple images from many sources and changing them into a single image with clearer more accurate information. techniques have been proposed to enhance distorted input using smooth filter improve the clarity of images. This work fused resulting filters (half left half right) size windows (3×3), (5×5), (7×7), (9×9), (11×11) pixels. The towards right was combined traditional such as addition, multiplication, new suggested techniques, namely absolute real standard...

The increasing demand for optical sensors is driven by their wide applications, making surface plasmon resonance (SPR) play a crucial role in this field. In study, multilayered thin film consisting of tantalum pentoxide (Ta2O5) and silver (Ag) deposited on glass prism was used to study SPR. Ag layer thickness fixed at 50 nm, while the Ta2O5 varied from 0 70 nm. Kretschmann configuration employed assess sensitivity air gases with different refractive indices. Therefore, thicknesses along...
