Visual augmentation of regions within images

A computing device tomography system, comprising:

• a radiation source;
• a detector array;
• an image reconstructor configured to generate a three-dimensional image of an object;
• and
• an item detection component configured to:
• identify an item within a first region of the three-dimensional image as a potential item of interest by comparing features of items depicted within the three-dimensional image to predefined features of an item of interest to be detected;
• responsive to determining that features of the item match the predefined features within a threshold amount, identify a second region proximate to the first region comprising the item based upon a location of the second region corresponding to where a connected part of the item is predicted to be located;
• apply a visual augmentation to the second region to visually distinguish the second region from other regions depicted within the image to create an augmented image;
• and
• render the augmented image through a display.

A non-transitory computer-readable medium comprising computer-executable instructions that when executed via a processing unit cause performance of operations, the operations comprising:

• identifying a first item depicted within a first region of an image of an object based upon the first item having a density above a threshold value;
• determining that the first item has a probability equal to at least a threshold amount of being part of a target item to be detected;
• selecting a second region proximate to the first region, the second region selected as a function of an orientation of the first item;
• evaluating the second region to determine whether a second item is present within the second region;
• and
• upon determining that the second item is present within the second region, grouping voxels of the first item with voxels of the second item such that the first item and the second item are treated as a single item.
