Segmentation-Based Image Processing For Confluency Estimation

An apparatus comprising:

• memory hardware configured to store computer-executable instructions;
• and
• processing hardware configured to execute the computer-executable instructions to:
• generate a first segmentation mask by segmenting an image;
• generate a modified mask by applying a morphological operation to the first segmentation mask;
• generate a modified masked input based on the image and an inversion of the modified mask;
• generate a second segmentation mask by segmenting the modified masked input;
• combine the first segmentation mask and the second segmentation mask to generate a composite mask;
• and
• determine a coverage of the image based on the first segmentation mask and the second segmentation mask, wherein determining the coverage includes estimating coverage of the composite mask.

An apparatus comprising:

• memory hardware configured to store computer-executable instructions;
• and
• processing hardware configured to execute the computer-executable instructions to:
• increasing a local contrast level of an image by applying a contrast-limited adaptive histogram equalization to the image, to generate an adjusted image;
• generate a first segmentation mask by segmenting the adjusted image;
• generate a modified mask by applying a morphological operation to the first segmentation mask;
• generate a modified masked input based on the image and an inversion of the modified mask;
• generate a second segmentation mask by segmenting the modified masked input;
• and
• determine a coverage of the image based on the first segmentation mask and the second segmentation mask.
