Abstract
An apparatus comprises a processor and a memory having computer readable instructions stored thereon. The computer readable instructions, when executed by the processor, cause the apparatus to capture, via an image sensor of a tool installed at least partially within a catheter, a first image within a lumen of the catheter. The first image comprises a plurality of pixels. The instructions further cause the apparatus to identify a first subset of the pixels comprising a viewable feature, and a second subset of the pixels comprising a background color. The instructions further cause the apparatus to adjust the second subset to a neutral color, create a modified image by filtering the pixels to remove the second subset, determine an angular orientation of the viewable feature in the modified image, and determine a rotational offset of the tool relative to the catheter based on the angular orientation of the viewable feature.
