X-ray baggage and parcel inspection system with efficient third-party image processing

A customized system for X-ray inspection image display comprising:

• an X-ray inspection image display system comprising:
• one or more processors;
• and
• one or more non-transitory computer readable storage media;
• and
• an X-ray inspection system including an X-ray scanner and an X-ray inspection system computer programmed to colorize a monochrome X-ray inspection image acquired by the X-ray scanner according to an X-ray inspection system false colorization scheme to generate a colorized X-ray inspection image;
• wherein the X-ray inspection image display system and the X-ray inspection system are operatively connected, and the X-ray inspection image display system is configured to receive the colorized X-ray inspection image by instructions that are readable and executable by the one or more processors to receive the colorized X-ray inspection image.

The customized system of 11, wherein the program instructions including instructions to filter the colorized X-ray inspection image by performing pixel shading on the colorized X-ray inspection image to generate a custom colorized X-ray inspection image having a custom false colorization scheme, further comprising one or more of the following program instructions, stored on the one or more non-transitory computer readable storage media, to:

• for each pixel of a plurality of pixels of the colorized X-ray inspection image to be filtered:
• for each basis vector, compute a cosine of an angle θ between a basis vector Vbasis having a length ∥Vbasis∥ and a pixel color vector Vpixel representing a color of the pixel to be filtered and having a length ∥Vpixel∥ according to:
• cos
• ⁢
• ⁢
• θ
• =
• V
• basis
• ·
• V
• pixel
• 
• V
• basis
• 
• ×
• 
• V
• pixel
• 
• wherein Vbasis·Vpixel is a dot product between the basis vector and the pixel color vector;
• and
• assigning the pixel to be filtered to a material of a set of materials for which cos θ is largest.
