Generating composite image from multiple images captured for subject

A system for generating a composite image, the system comprising:

• an image capturing device configured to capture a plurality of sets of images of at least a portion of a subject,;
• and
• an image processing device configured to:
• receive the plurality of sets images from the image capturing device;
• combine the images associated with each of the plurality of sets of images to generate a plurality of focus-stacked images corresponding to the plurality of sets of images;
• align the plurality of focus-stacked images in a horizontal plane;
• and
• upon aligning, perform position correction on the plurality of focus-stacked images to generate a composite image by identifying an overlapped region between the pair of adjacent focus-stacked images upon aligning the plurality of focus-stacked images using a horizontal coordinate transformation model, based on one or more calibration parameters.

A non-transitory computer-readable medium storing computer-executable instructions for generating a composite image, the computer-executable instructions configured for:

• receiving, via an image capturing device, a plurality of sets of images of at least a portion of a subject;
• combining the images associated with each of the plurality of sets of images to generate a plurality of focus-stacked images corresponding to the plurality of sets of images;
• aligning the plurality of focus-stacked images in the horizontal plane;
• and
• upon aligning, performing position correction on the plurality of focus-stacked images to generate a composite image representing the subject by identifying an overlapped region between the pair of adjacent focus-stacked images upon aligning the plurality of focus-stacked images using a horizontal coordinate transformation model, based on one or more calibration parameters.
