I think only ideal, exact solutions are enough. Range of S, could be anything, from 1 node to all nodes in G. We can take our time doing any calculations, even if its 5 seconds and have a very strong processor.

I was thinking about this, and what I had in mind is first we pick a random node in S, and do a BFS traversal from that node, basically storing 2 pieces of data in every node. First is the smallest distance from the current node to the starting node, and a reference of the previous node to the...

I have a unique problem and looking for a known fast algorithm for it. I have an unweighted but directed graph `G`. I then have a subset collection of nodes `S` existing in `G`. I want to find the minimum sub tree in `G` such that it contains all the nodes in `S`. I so far found Chu-Liu/Edmonds...

For starters the prototype would be developed by me so I can use, but it could potentially be used by others to assemble and use, so just looking for simplicity.

It could work, but I'm also looking to minimize other factors. Your idea would increase material compared to my idea. It would need an extra base on top. Then you would need to cut a hole in it, then construct that alignment piece and stick it on the base. It just seems like it would be more...

oh ok, so that whole thing would be on top, but it looks like there is a lot of extra material needed for the top then. I was looking to minimize on material used. In my example, I have two L shape sticks, which is much less material.

It's a bit confusing because it looks like the phone is flat on the ground. How would it take the picture of the object, and where would the object be?

True, the images will need the same lighting without shadow. So that would mean the light source should come from the camera. Maybe I can just use the camera flash to handle that. The objects will basically be food items from restaurants, so it should be safe to assume the biggest will probably...

x is probably going to be around 1.5-2 feet. The location of the phone should be such that when the camera takes the picture, the center of the image should align with the center of the object. I don't have any exact numbers for precision, but it should basically be as close as possible to...

I have a project which requires me to get 5 very specific images of an object from various angles. The user can't use their hands because it would be too shakey and introduce error. These images have to be precise and steady. So that's why I need to build a helper camera mounting device to help...

I was able to fix it, using three methods. The issue was numerical unstability in the quadratic function to calculate the y coordinate. 1. Use the much more stable quadratic formula http://www.it.uom.gr/teaching/linearalgebra/NumericalRecipiesInC/c5-6.pdf 2. translate the square to location...

I did a test and tried to warp an image and this seems to work in general, but then in two places the formula messed up. See these two pics. The left eye got messed and the right leg got messed too. The above example quad is for the right leg. original: warped: using this warp template:

I added the missing image above. And the matrix is based off the pdf file on page 4. X = a0 + a1U + a2V + a3UV Y = b0 + b1U + b2V + b3UV Where X, and Y is coordinates on the quad, and U,V and coordinates on the square. By substituting the 4 pairs of corresponding corner coordinates, I get 8...

I want to try this bilinear transformation of a rectangle to a quad described here http://www.fmwconcepts.com/imagemagick/bilinearwarp/FourCornerImageWarp2.pdf on page 4. I have the square $$(500,900)(599,900)(599,999)(500,999)$$ and the quad $$(454,945)(558,951)(598,999)(499,999)$$ It...
