学习OpenCV——grabcut_综合

GrabCut函数说明

Parameters:	image – Input 8-bit 3-channel image. mask – Input/output 8-bit single-channel mask. The mask is initialized by the function when`mode` is set to `GC_INIT_WITH_RECT`. Its elements may have one of following values: GC_BGD defines an obvious background pixels. GC_FGD defines an obvious foreground (object) pixel. GC_PR_BGD defines a possible background pixel. GC_PR_BGD defines a possible foreground pixel. rect – ROI containing a segmented object. The pixels outside of the ROI are marked as “obvious background”. The parameter is only used when`mode==GC_INIT_WITH_RECT` . bgdModel – Temporary array for the background model. Do not modify it while you are processing the same image. fgdModel – Temporary arrays for the foreground model. Do not modify it while you are processing the same image. iterCount – Number of iterations the algorithm should make before returning the result. Note that the result can be refined with further calls with`mode==GC_INIT_WITH_MASK` or`mode==GC_EVAL` . mode – Operation mode that could be one of the following: GC_INIT_WITH_RECT The function initializes the state and the mask using the provided rectangle. After that it runs`iterCount` iterations of the algorithm. GC_INIT_WITH_MASK The function initi

Parameters:

image – Input 8-bit 3-channel image.
mask –
Input/output 8-bit single-channel mask. The mask is initialized by the function whenmode is set to GC_INIT_WITH_RECT. Its elements may have one of following values:
- GC_BGD defines an obvious background pixels.
- GC_FGD defines an obvious foreground (object) pixel.
- GC_PR_BGD defines a possible background pixel.
- GC_PR_BGD defines a possible foreground pixel.
rect – ROI containing a segmented object. The pixels outside of the ROI are marked as “obvious background”. The parameter is only used whenmode==GC_INIT_WITH_RECT .
bgdModel – Temporary array for the background model. Do not modify it while you are processing the same image.
fgdModel – Temporary arrays for the foreground model. Do not modify it while you are processing the same image.
iterCount – Number of iterations the algorithm should make before returning the result. Note that the result can be refined with further calls withmode==GC_INIT_WITH_MASK ormode==GC_EVAL .
