Abstract

Disclosed are processes including receiving at least a first and a second image data record corresponding to a first and a second point in time and including a first and a second one or more images of a wound; obtaining an image of the wound from a particular point of view corresponding to the first point in time by analyzing the first image data record; generating a simulated image of the wound from the particular point of view corresponding to the second point in time by analyzing the second image data record; and generating a visual time series view of the wound including at least the image of the wound from the particular point of view corresponding to the first point in time and the simulated image of the wound from the particular point of view corresponding to the second point in time.

First claim

What is claimed is:

1. A non-transitory computer readable medium storing data and computer implementable instructions that, when executed by at least one processor, cause the at least one processor to perform operations for generating visual time series views of wounds, the operations comprising:
receiving at least a first image data record and a second image data record, the first image data record corresponding to a first point in time and including a first one or more images of a wound captured at the first point in time, and the second image data record corresponding to a second point in time and including a second one or more images of the wound captured at the second point in time;
obtaining an image of the wound from a particular point of view corresponding to the first point in time by analyzing the first image data record;
generating a simulated image of the wound from the particular point of view corresponding to the second point in time by analyzing the second image data record, wherein the second one or more images of the wound do not include an image of the wound from the particular point of view; and
generating a visual time series view of the wound including at least the image of the wound from the particular point of view corresponding to the first point in time and the simulated image of the wound from the particular point of view corresponding to the second point in time.

2. The non-transitory computer readable medium of claim 1 , wherein the image of the wound from the particular point of view corresponding to the first point in time is a simulated image of the wound based on the first image data record.

3. The non-transitory computer readable medium of claim 1 , wherein the image of the wound from the particular point of view corresponding to the first point in time is an image of the first one or more images of the wound.

4. The non-transitory computer readable medium of claim 1 , wherein the second image data record includes motion data captured using an accelerometer associated with an image sensor used to capture the second one or more images of the wound, and wherein the analyzing the second image data record includes analyzing the motion data.

5. The non-transitory computer readable medium of claim 1 , wherein generating the simulated image of the wound from the particular point of view corresponding to the second point in time includes generating the simulated image to have selected illumination characteristics.

6. The non-transitory computer readable medium of claim 5 , wherein generating the simulated image of the wound from the particular point of view corresponding to the second point in time further includes analyzing the image of the wound from the particular point of view corresponding to the first point in time to select the selected illumination characteristics.

7. The non-transitory computer readable medium of claim 1 , wherein the images of the wound from the particular point of view corresponding to the first point in time and to the second point in time both correspond to a same treatment phase of a treatment cycle of the wound.

8. The non-transitory computer readable medium of claim 7 , wherein generating the simulated image of the wound from the particular point of view corresponding to the second point in time further includes:
analyzing the image of the wound from the particular point of view corresponding to the first point in time to determine a treatment phase of the treatment cycle of the wound corresponding to the image of the wound from the particular point of view corresponding to the first point in time; and
generating the simulated image of the wound from the particular point of view corresponding to the second point in time to correspond to the determined treatment phase.

9. The non-transitory computer readable medium of claim 1 , wherein each image of the images in the visual time series view of the wound corresponds to a point in time, and the images in the visual time series view of the wound are ordered based on the corresponding points in time.

10. The non-transitory computer readable medium of claim 1 , wherein the images of the wound from the particular point of view corresponding to the first point in time and to the second point in time both correspond to a same distance from the wound.

11. The non-transitory computer readable medium of claim 10 , wherein generating the simulated image of the wound from the particular point of view corresponding to the second point in time includes generating the simulated image of the wound from the particular point of view corresponding to the second point in time by causing a distance from the wound in the simulated image to be equal to the distance from the wound associated with the image of the wound from the particular point of view corresponding to the first point in time.

12. The non-transitory computer readable medium of claim 1 , wherein the images of the wound from the particular point of view corresponding to the first point in time and to the second point in time both have a same spatial orientation.

13. The non-transitory computer readable medium of claim 12 , wherein generating the simulated image of the wound from the particular point of view corresponding to the second point in time includes generating the simulated image of the wound from the particular point of view corresponding to the second point in time by causing a spatial orientation in the simulated image to be equal to a spatial orientation associated with the image of the wound from the particular point of view corresponding to the first point in time.

14. The non-transitory computer readable medium of claim 1 , wherein pixels of at least one matching pair of pixels of the image of the wound from the particular point of view corresponding to the first point in time and from the simulated image of the wound from the particular point of view corresponding to the second point in time correspond to a same physical length.

15. The non-transitory computer readable medium of claim 1 , the operations further comprising:
calculating a convolution of a part of an image of the first one or more images to derive a first result value;
calculating a convolution of a part of an image of the second one or more images to derive a second result value; and
determining a value of at least one pixel of the simulated image of the wound from the particular point of view corresponding to the second point in time based on the first result value and the second result value.

16. The non-transitory computer readable medium of claim 1 , the operations further comprising:
analyzing a first image of the first one or more images to detect a region of the wound corresponding to a particular tissue type in the first image;
analyzing a second image of the second one or more images to detect a region of the wound corresponding to the particular tissue type in the second image; and
determining a value of at least one pixel of the simulated image of the wound from the particular point of view corresponding to the second point in time based on the region of the wound corresponding to the particular tissue type in the first image and the region of the wound corresponding to the particular tissue type in the second image.

17. The non-transitory computer readable medium of claim 1 , wherein each particular image of the wound from the particular point of view corresponding to the first point in time and to the second point in time includes a visual indicator of a region of the wound corresponding to a particular tissue type in the particular image
