Object identification system and method

A computer implemented object detection system comprising:

• a data repository configured to store an object detection dataset;
• an input interface configured to receive a training image dataset comprising a plurality of images that include objects of interest, each image comprising pixel values corresponding to an imaged material generated by a penetrating imager;
• a processor configured to execute computer program code for executing an image processor, including:
• computer program code configured to generate a thresholded image for each of the plurality of images in the training image dataset;
• computer program code configured to segment each thresholded image into images corresponding to objects;
• computer program code configured to create a greyscale image per object from the segmented images corresponding to that object by, for multiple segmented images of a respective object, calculating an average pixel value for each pixel of the object from corresponding pixels of the object in the respective multiple segmented images;
• computer program code configured to form a greyscale image for the object from the averaged pixels;
• computer program code configured to store the greyscale images in a data repository as an object detection dataset;
• and
• computer program code configured to update the grayscale image by adding further segmented images of the object and recalculating the average.
