I have a bunch of images in MrSID format (150 or more) with sizes from 3Mb to 10Mb each, and I need to get the bounding box that contains them all.

What is the fastest way of doing it?

My approach is as shown in the picture. It takes 1 minute for 3 .sid files (6Mb each). If reading a single SID file is slow, let alone 150. There must be some better way of doing this. Any idea?

Is there significant difference on processing time between the workspace containing a BoundingBoxAccumulator and the workspace just reading the source images without creating bounding box?

 

 

Why not inspect features with Visual/Data Preview and Feature/Record Information before writing them into a destination dataset?

Besides, looks like you have run the workspace with Feature Caching. Feature Caching is convenient to debug, but it takes a long time to process since it cashes every feature on the workflow. I expect that the process would be much faster if you uncheck the Feature Caching option.

 

Anyway, I don't think the BoundingBoxAccummulator would be a major issue on the performance .
