Abstract
Techniques for densifying annotations associated with sensor data are discussed herein. For example, techniques may include projecting a subset of lidar points into an unannotated two-dimensional image. Based on the projecting, the annotations of lidar points projected into the image can be associated with the image data. A subset of pixels of pixels can be dilated, and the dilated pixels can be determined to intersect (e.g., overlap, touch, etc.). Based on the pixels intersecting (or being adjacent) and being associated with the same segment identifier, a contour can be rendered around the corresponding non-dilated pixels to identify an object in the image data.
