Blob Analyzer Dark Segmentation The Dark Segmentation algorithm is the inverse function of the Light segmentation algorithm. The Blob Analyzer outputs all pixels with values below the threshold value as blob pixels. Pixels with values above the threshold become background pixels. This mode is used for dark blobs on a light background. Inside Segmentation The Inside Segmentation algorithm uses a dual-threshold function. Only pixels with grey- level values within the threshold range are output as blob pixels. This mode is used when the pixel values of blobs fall somewhere between the values of the object and the image back- ground.
Outside Segmentation The Outside Segmentation operates as an inverse function of the Inside Segmentation mode. Pixel values that fall outside the threshold range are output as blob pixels. This is use- ful for situations where blobs can be either very dark or very light when compared to the back- ground. Configuration Refer also to Configuring Blob Analyzer Properties on page 404. ACEUser's Guide, 3.6.x, 18316-000 Rev A Page 402 Object Definition Properties Allow Clipped Blobs Enables the inclusion of clipped blobs into the res- ult set. Maximum Blob Count The maximum number of blobs that the tool returns. Results Display Mode Defines how the results are displayed in the image display.
The following options are avail- able: Markers l Blob Image l Both l Segmentation Parameters Segmentation parameters used by the tool to loc- ate the blob. Refer to Image Segmentation.
