1. A computer-implemented method for efficiently and accurately locating features of interest in warped images, the computer-implemented method comprising: rendering, by an image rendering application hosted on a computing device, a source image and a first graphical user interface (GUI) element that identifies a feature of interest in the source image; accessing, by the image rendering application, a destination image, wherein the destination image is generated from the source image by warping at least a portion of the source image based on a backward map, wherein the backward map maps points from a mesh of the destination image to pixels from the source image, wherein the points of the mesh are arranged in tiles; generating, by the image rendering application, triangles from the tiles, wherein the triangles form a new mesh; generating, by the image rendering application, a forward map based on the triangles of the new mesh and the backward map, wherein the forward map maps points from a mesh of the source image to pixels from the destination image; identifying, by the image rendering application, a point from the mesh of the source image, wherein the point corresponds to a pixel of the source image and is associated with the feature of interest; locating, by the image rendering application, a pixel from the destination image based on the identified point and the forward map; associating, by the image rendering application, the located pixel in the destination image with the feature of interest; and rendering, by the image rendering application, the destination image and a second GUI element that identifies the feature of interest in the rendered destination image based on the located pixel in the destination image.
