Brightness and Contrast Modification in Ultrasonography Images Using Edge Detection Results
Abstract: Currently,
ultrasonography device become important equipment for supporting diagnosis in diesases.
Unfortunetaly, a lot of ultrasonography images do not provide enough
information for supporting diagnosis especially images produced by
low-resolution ultrasonography. It is caused by image quality that has been
produced is inadequate because of noise. This research aims to improve image
quality bymodifying brightness and contrast to the edge detection algorithms.
By modifying the brightness andcontrast will cause the value of standard
deviation of the ultrasonography image is lowered. Raising setting values will
cause deviation standard value become smaller, and also the result of standard
deviation is inversely proportional to the value of RMSE. The results show that
this modification can improve image quality by reducing noise significantly.
