| Thank you for your version, Chris. Of course my code is very sloppy. The short version is[mcode]components = MorphologicalComponents[ MorphologicalPerimeter[Binarize[image, {0.225, 0.275}], CornerNeighbors -> True], 0, CornerNeighbors ->... |
| I like the function DistanceTransform. If you are lazy enough, this function provides a lot of "cheap" solutions for complex geometrical problems. For example, one can find the closest pair between two arbitrary set if pixels:[mcode]dimensions =... |
| Is it what you want?[mcode]points = Transpose[{Table[ Cos[1/2 \[Theta]], {\[Theta], 0, \[Pi], \[Pi]/2000}], Table[Sin[\[Theta]]^2, {\[Theta], 0, \[Pi], \[Pi]/2000}], Table[Sin[3 \[Theta]]^3, {\[Theta], 0, \[Pi], \[Pi]/2000}]}]; ... |
| I wouldn't say "correct". JPEG is not a representation it is a lossy compression algorithm, thus the command "Save as JPEG" equals to "delete some infomation". But it is a mystery for me why the option "CompressionLevel" -> 0 results in a file which... |
| One more comment. In order to extract position you can use:morph = ImageMultiply[ImageMultiply[minFilter, 10], ImageMultiply[GaussianFilter[MorphologicalBinarize[ImageMultiply[minFilter, 10]],5], 2]]and then[mcode]ImageAdd[image,... |
| There is possibility that you do not have scanner at the moment and you made a photo of a document with your camera. Here is a small program how you can improve the photo especially if there is nonuniform light and shadows. I found the key idea in... |
| I tried inpaiting for a very simple example with grid lines and as expected it doesn't work well:[mcode]SetDirectory[NotebookDirectory[]]; initial = Import["Notebook... |
