Calculation of correction values for white balancing
Contrast enhancement using histogram equalization
Global thresholding (often used in the area of image segmentation)
Histogram in the GigEVisionSDK
In the GigEVisionSDK the ImageProcAPI provides the programming interface to generate histogram data
from images. The bit depth and image types supported by the histogram feature are shown in Table 80. For a
detailed description on how to instantiate this feature in user applications please refer to the GigEVisionSDK
API Help located in the doc folder of the GigEVisionSDK installation directory.
