PATCH GENERATION IN REGION OF INTEREST
In a method for capturing patches in an image, a processor receives an image comprising a region of interest. A processor captures a first patch pattern. The first patch pattern may include a first point-centered patch that is centered on a first center point inside the region of interest and a first point-edged patch that is located with a patch edge contacting the first center point. A processor selects a second center point that is inside the region of interest and outside the first patch pattern. A processor captures a second patch pattern. The second patch pattern may include a second point-centered patch that is centered on the second center point, and a second point-edged patch that is located with a patch edge contacting the second center point.
1 . A computer-implemented method for capturing patches, comprising:
receiving, at a processor, an image comprising a region of interest;
capturing a first patch pattern, wherein the first patch pattern comprises:
a first point-centered patch that is centered on a first center point inside the region of interest; and
a first point-edged patch that is located with a patch edge contacting the first center point;
selecting a second center point that is inside the region of interest and outside the first patch pattern; and
capturing a second patch pattern, wherein the second patch pattern comprises:
a second point-centered patch that is centered on the second center point; and
a second point-edged patch that is located with a patch edge contacting the second center point.
2 . The method of claim 1 , wherein the first patch pattern comprises a second point-centered patch that is rotated at an angle relative to the first point-centered patch, wherein the angle is greater than 0 degrees and less than 90 degrees.
3 . The method of claim 1 , wherein the first point-edged patch comprises a selection from the group consisting of: a patch with a left edge contacting the first center point, a patch with a right edge contacting the first center point, a patch with a bottom edge contacting the first center point, and a patch with a top edge contacting the first center point.
4 . The method of claim 1 , wherein the first patch pattern comprises a patch with a left edge contacting the first center point, a patch with a right edge contacting the first center point, a patch with a bottom edge contacting the first center point, and a patch with a top edge contacting the first center point.
5 . The method of claim 1 , wherein the first center point comprises a centroid of the region of interest.
6 . The method of claim 1 , wherein selecting the second center point comprises comparing a pixel grayscale value to a grayscale threshold.
7 . The method of claim 1 , wherein the image comprises a selection from the group consisting of: a segmentation heatmap image, a binary mask, and a gray-scale image.
8 . A computer program product for capturing patches in an image, the computer program product comprising:
one or more computer-readable storage media and program instructions stored on the one or more computer-readable storage media, the program instructions comprising:
program instructions to receive, at a processor, an image comprising a region of interest;
program instructions to capture a first patch pattern, wherein the first patch pattern comprises:
a first point-centered patch that is centered on a first center point inside the region of interest; and
a first point-edged patch that is located with a patch edge contacting the first center point;
program instructions to select a second center point that is inside the region of interest and outside the first patch pattern; and
program instructions to capture a second patch pattern, wherein the second patch pattern comprises:
a second point-centered patch that is centered on the second center point; and
a second point-edged patch that is located with a patch edge contacting the second center point.
9 . The computer program product of claim 8 , wherein the first patch pattern comprises a second point-centered patch that is rotated at an angle relative to the first point-centered patch, wherein the angle is greater than 0 degrees and less than 90 degrees.
10 . The computer program product of claim 8 , wherein the first point-edged patch comprises a selection from the group consisting of: a patch with a left edge contacting the first center point, a patch with a right edge contacting the first center point, a patch with a bottom edge contacting the first center point, and a patch with a top edge contacting the first center point.
11 . The computer program product of claim 8 , wherein the first patch pattern comprises a patch with a left edge contacting the first center point, a patch with a right edge contacting the first center point, a patch with a bottom edge contacting the first center point, and a patch with a top edge contacting the first center point.
12 . The computer program product of claim 8 , wherein the first center point comprises a centroid of the region of interest.
13 . The computer program product of claim 8 , wherein selecting the second center point comprises comparing a pixel grayscale value to a grayscale threshold.
14 . The computer program product of claim 8 , wherein the image comprises a selection from the group consisting of a segmentation heatmap image, a binary mask, and a gray-scale image.
15 . A computer system for capturing patches in an image, the computer system comprising:
one or more computer processors, one or more computer-readable storage media, and program instructions stored on the computer-readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
program instructions to receive, at a processor, an image comprising a region of interest;
program instructions to capture a first patch pattern, wherein the first patch pattern comprises:
a first point-centered patch that is centered on a first center point inside the region of interest; and
a first point-edged patch that is located with a patch edge contacting the first center point;
program instructions to select a second center point that is inside the region of interest and outside the first patch pattern; and
program instructions to capture a second patch pattern, wherein the second patch pattern comprises:
a second point-centered patch that is centered on the second center point; and
a second point-edged patch that is located with a patch edge contacting the second center point.
16 . The system of claim 15 , wherein the first patch pattern comprises a second point-centered patch that is rotated at an angle relative to the first point-centered patch, wherein the angle is greater than 0 degrees and less than 90 degrees.
17 . The system of claim 15 , wherein the first point-edged patch comprises a selection from the group consisting of: a patch with a left edge contacting the first center point, a patch with a right edge contacting the first center point, a patch with a bottom edge contacting the first center point, and a patch with a top edge contacting the first center point.
18 . The system of claim 15 , wherein the first patch pattern comprises a patch with a left edge contacting the first center point, a patch with a right edge contacting the first center point, a patch with a bottom edge contacting the first center point, and a patch with a top edge contacting the first center point.
