Blob Analyzer contours. As illustrated in the following figure, a detail from a non-interpolated image shows a blob's contour as being very jagged and irregular. Effect of Bilinear Interpolation on Blob Detection Blob Sorting Blob Sorting enables the sorting of blob instances, as displayed in the results grid. When No Sorting is selected (default), blob instances are presented in the order in which they are found by the Blob Analyzer. Otherwise, blobs are sorted according to the sort criteria you set. By default, results are displayed in descending order. You can override this by checking Ascending in the criteria drop-down box. See the following figure.
