Lacey Carbon Application¶

Lacey carbon support has irregular size of holes. Making it difficult to find effiiciently the good area to target.

Possible strategies:

Manual Targeting, and queue it up.¶

pro: minimal false positive and false negative. You decide where you want regarding spacing of the targets and distance from the edge.
con: user time-consuming. You have to do this at Exposure Targeting Node for every hl image coming in.

Using MSI-T application to collect Lacey Carbon support data¶

pro: low false positive. Find most holes on the image and take image at the center of each.
con: high false negative. Can not vary the number of images taken in each hole according to the hole size. Focus may fail when it offset to an empty area.

RasterFC Lacey carbon rastering¶

This is a published node class developed by W.V. Nicholson, H. White and J. Trinick (2010) JSB 172, 395-399.

pro: Raster through the hl image giving maximal number of images.
con: high false positive. May take many images on the support film.
