Image Enhancement
The tool of image enhancement includes sharpness, contrast adjustment, Gamma adjustment, and
brightness adjustment.
Image Enhancement
Sharpness
Image sharpening is to highlight the edges, contours, and features of some linear target
elements on the image. This filtering method improves the contrast between the edge of the
object and the surrounding pixels, so it is also called edge enhancement.
It has two parameters, including sharpen intensity and kernel size. The larger value of sharpen
intensity, and the sharper the image is. The range of kernel size is between 1 and 51.
Contrast
Image contrast is the perception of the difference in image color and brightness. The greater the
contrast, the greater the difference between the object and the surroundings of the image, and
vice versa.
Contrast coefficient: it is a common parameter, and is used to control contrast coefficient. 100
stands for not adjustment, and the number is larger than 100, it means that contrast increases.
Otherwise, it means that contrast reduces.
Gamma
it is a common parameter, and 1 refers to effect without adjustment. Gamma adjustment is used
to edit the gamma curve of the image to achieve non-linear tone editing of the image. It can
detect the dark portion and the light portion of the image signal, increase their ratio, thus
improving Image contrast effect. But, the too large parameter will make the picture dark.
If the Gamma is between 0 and 1, the dark area of the image will become bright.
if the Gamma is between 1 and 4, the dark area of the image will become dark.
