EOCV::GetSampleBackground
EOCV::SetSampleBackground
Reference background gray levels determined during inspection of the sample.
Namespace: Euresys::Open_eVision_2_5
[C++]
float GetSampleBackground()
void SetSampleBackground(float value)
Remarks
Image contrast is an important factor during both learning and inspection. The background and foreground information must be separated using an appropriate threshold, possibly determined automatically. After a threshold is given, the average gray level of the background and foreground areas are computed separately. These serve as reference gray levels to measure the image contrast and normalize the gray level quality indicators. The background and foreground reference gray levels are computed for both the template and sample images. They are used for contrast assessment as well as gray-level normalization.
