Basic Parameters

• Category Name: It is usually used with DL image segmentation. Subscribe to the category

name of DL image segmentation, or manually output a group of category names.

• Gray Value: It is usually used with DL image segmentation. Subscribe to the gray value of

Running Parameters

• Number of Fund Blobs: it is used to set the number of Blob graphs to find.

• Area Enable: After enabled, it is limited to find the area range of Blob.

• Contour Enable: After enabled, the module show the Blob contour.

• Blob Image Output: After disabled, the image after Blob analysis do not output any more.

• Perimeter, Short Axis, Long Axis, Circularity, Rectangularity, Barycenter Offset, Axis

Ratio: see BLOB Analysis for details.

• Axial Ratio Range: short axis of box: long axis of box

• Sort Feature: it has several characteristics, such as area, perimeter, circularity,

rectangularity, connected domain center x, connected domain center y, box angle, box width, box

height, rectangular upper left vertex x, rectangular upper left vertex y, second-order center distance,

principal axis angle, axis ratio, etc.

• Sort Mode: ascending, descending and non sorting are used in combination with the sorting

feature.

• Connectivity: In image processing, the object we are interested in is usually a combination

of interconnected pixels. Therefore, in order to obtain an area, we must calculate all the connected

areas that are contained in the area after division. On a rectangular pixel grid, there are two

definitions of connectivity. The first one is that the two pixels have a common edge, that is, one

pixel is above, below, to the left or to the right of the other pixel, which is called 4-connectivity. The

second definition is the extension of the first definition. The adjacent pixels on the diagonal line are

also included, which is called 8-connectivity.
