cameraImageAdjust

Adjusts non-uniform images with white background. Intended for use on full-tissue histological images.

This function is intended for use with medical images of samples taken

with a handheld camera or brightfield microscope. Regardless of

acquisition modality, the background must be bright (i.e. near the pixel

maximum). Using these images and a mask to denote the background area,

this function modifies input images to adjust for inconsistent or

non-uniform lighting in the background. The sample is removed from the

image using the background mask and the gap is filled in. All pixels are

increased to the highest possible pixel value and the sample is

added back in over the calibrated background image.

INPUTS

images - uint8 single image or cell - must be color (will be changed in

version 2)

bkgndMask - logical single image or cell - size must match images

OUTPUTS

images - in-place optimization used to conserve memory on large sets

DIRECTIONS FOR USE

Use the image segmenter app or manual code to segment the background from

the image. Ensure that no part of the sample is included in the

background mask. Use the raw image as the first input and the background

logical mask as the second input. The resultant image will be the

calibrated image. No other outputs are provided.
