image-stitching

问题 I'm displaying a texture on a cube (see SceneKit - Map cube texture to box) Things work well now, but the result show a light stitching line between some of the cube faces that I outlined here (you are inside the cube): Any idea how I can get rid of that? The input texture looks like So there is some discontinuity in the input. I'm using a custom SceneKit geometry that doesn't do much more than mapping this texture to a cube. You can find the relevant code in question mentioned above: https:/

问题 I am trying to write an algorithm (in c#) that will stitch two or more unrelated heightmaps together so there is no visible seam between the maps. Basically I want to mimic the functionality found on this page : http://www.bundysoft.com/wiki/doku.php?id=tutorials:l3dt:stitching_heightmaps (You can just look at the pictures to get the gist of what I'm talking about) I also want to be able to take a single heightmap and alter it so it can be tiled, in order to create an endless world (All of

问题 I found simple code in python for image registration here in simple case of translation we have: def translation(im0, im1): """Return translation vector to register images.""" shape = im0.shape f0 = fft2(im0) f1 = fft2(im1) ir = abs(ifft2((f0 * f1.conjugate()) / (abs(f0) * abs(f1)))) t0, t1 = numpy.unravel_index(numpy.argmax(ir), shape) if t0 > shape[0] // 2: t0 -= shape[0] if t1 > shape[1] // 2: t1 -= shape[1] return [t0, t1] but I don't understand this part: if t0 > shape[0] // 2: t0 -=

问题 I am using following code to stitch to input images. For an unknown reason the output result is crap! It seems that the homography matrix is wrong (or is affected wrongly) because the transformed image is like an "exploited star"! I have commented the part that I guess is the source of the problem but I cannot realize it. Any help or point is appriciated! Have a nice day, Ali void Stitch2Image(IplImage *mImage1, IplImage *mImage2) { // Convert input images to gray IplImage* gray1 =

问题 I'm trying to reduce the calculation time of my stitching algorithm. I got some images which I want to stitch in a defined order but it seems like cv::stitcher.stitch() function tries to stitch every image with every other image. I feel like I might find the solution in the parameters of OpenCV Stitcher. If not maybe I have to modify the function or try something else to reduce calculation time. But since I'm pretty much a beginner, I don't know how. I know that using GPU might be a
