METHOD AND SYSTEM FOR FAST VOLUME CROPPING OF THREE-DIMENSIONAL IMAGE DATA

A method for quickly identifying object volumetric data and air volumetric data from image data of an object is disclosed. Significantly, embodiments of the method result in significant savings in disk space and a significant reduction in computer processing time as compared to the types of known three-dimensional image processing methods described above. An explosive detection system is also provided that includes computer executable instructions stored in a memory coupled with a computer processor. When executed by the computer processor, the computer executable instructions cause the computer processor to: operate the imaging system to obtain the image data of the object; sample the image data in three dimensions; identify one or more candidate voxels; and identify, from the one or more candidate voxels, one or more starting voxels.
