the operations further comprise transforming the non-infrared depth image to a coordinate system of the color image.
4. The system of claim 1 , wherein:
the depth sensing component includes an infrared camera;
the depth information includes an infrared depth image; and
the operations further comprise transforming the infrared depth image to a coordinate system of the color image.
5. The system of claim 1 , wherein:
the determining of the portion of the image includes identifying a set of planar pixels based on the depth information.
6. The system of claim 1 , wherein:
the determining of the portion of the image includes detecting a perimeter of the surgical textile based on the depth information.
7. The system of claim 1 , wherein:
the determining of the portion of the image includes detecting a vertical transition in the depth information.
8. The system of claim 1 , wherein the operations further comprise:
downsampling the depth information;
generating a mask image based on the downsampled depth information; and
upsampling the generated mask image; and wherein:
the determining of the portion of the image is based on the upsampled mask image.
9. The system of claim 1 , wherein the operations further comprise:
generating a mask image based on a perimeter of the surgical textile; and wherein:
the determining of the portion of the image is based on the generated mask image.
10. A method comprising:
accessing, by one or more processors, a color image that depicts a surgical textile within a field of view;
accessing, by the one or more processors, depth information acquired from the field of view;
determining, by the one or more processors and based on the depth information, a portion of the color image in which the determined portion depicts the surgical textile; and
determining, by the one or more processors, blood information based on the portion of the color image.
11. The method of claim 10 , wherein:
the determining of the blood information includes estimating an amount of a blood component based on the portion of the image.
12. The method of claim 10 , wherein:
the depth information includes a non-infrared depth image; and
the method further comprises transforming the non-infrared depth image to a coordinate system of the color image.
13. The method of claim 10 , wherein:
the depth information includes an infrared depth image; and
the method further comprises transforming the infrared depth image to a coordinate system of the color image.
14. The method of claim 10 , wherein:
the determining of the portion of the image includes identifying a set of planar pixels based on the depth information.
15. The method of claim 10 , wherein:
the determining of the portion of the image includes detecting a perimeter of the surgical textile based on the depth information.
16. The method of claim 10 , wherein:
the determining of the portion of the image includes detecting a vertical transition in the depth information.
17. The method of claim 10 , further comprising:
downsampling the depth information;
generating a mask image based on the downsampled depth information; and
upsampling the generated mask image; and wherein:
the determining of the portion of the image is based on the upsampled mask image.
18. The method of claim 10 , further comprising:
generating a mask image based on a perimeter of the surgical textile; and wherein:
the determining of the portion of the image is based on the generated mask image.
19. A non-transitory machine-readable medium comprising instructions that, when executed by one or more processors of a machine, configure the machine to perform operations comprising:
accessing a color image that depicts a surgical textile within a field of view;
accessing depth information acquired from the field of view;
based on the depth information, determining a portion of the color image in which the determined portion depicts the surgical textile; and
determining blood information based on the portion of the color image.
20. The non-transitory machine-readable medium of claim 19 , wherein:
the depth information includes a non-infrared depth image; and
the operations further comprise transforming the non-infrared depth image to a coordinate system of the color image.
