Web Image Processing:

Summary

The functions of this web image processing module are:

• upload of image collections
• image tile calibration (flat field correction)
• image tile stitching
• image segmentation to obtain a binary mask
• pixel depth conversion to 8 bits per pixel
• image pyramid building for deep zoom viewing
• configuration of multiple image pyramids into a multiple layer deep zoom visualization
• image tesselation to create rectangular or hexagonal image partitions
• image assembly

The deep zoom viewer has additional interactive built-in functions in addition to the pan-zoom functionality. The additional functions are described at the NIST external URL and include:

• downloading raw or displayed image sub-sets
• displaying original and displayed image intensities
• transparent overlays of multiple layers
• interactive image filtering and connectivity analysis in a browser
• spatial scale measurements
