5.4. Image pre-processing
The image pre-processing refers to the operation separating
the rib-eye from the background in this study. This is a necessary
procedure for the segmentation of marbling, which is
composed of several operations such as thresholding, region
growing and morphological operation (Chen and Ji, 2007). This
study focuses on the development of a segmentation algorithm.
Thus the removal of background was not discussed in
detail here.
