How to convert following code to elixir code. I have made this program to detect digit and its position in a grid. I know how to make simple elixir programs but I dont know how to make such complex programs in elixir because I dont know the syntax and about the libraries used in elixir. I also se…

That’s not just converting Python to Elixir code, you also need an image processing library. This thread has a few references: Image processing library Though I’d probably prefer the one described here: Image - an image processing library based upon Vix …and by the same author, it even mentions e…

i want to do it using evision i have installed it in elixir but dont know which functions are available in evision similar to opencv so that i can use it accordingly

and what are there syntex, arguments and parameters.

The docs should provide that: Evision — Evision v1.0.0

def drawContours(path) do {:ok, imgGrey} =OpenCV.imread(path, flags: OpenCV.cv_IMREAD_GRAYSCALE()) {:ok, {_, thrash}} =OpenCV.threshold(imgGrey, 240, 255, OpenCV.cv_THRESH_BINARY()) {:ok, {contours, _}} =OpenCV.findContours(thrash, OpenCV.cv_RETR_TREE(), OpenCV.cv_CHAIN_APPROX_…

As shown in your code, the python code is drawing on a copy of the original image (3-channel BGR) while you were drawing contours on the thresholded image (1-channel image). So you can either draw contours on the original BGR image or change the color from {0, 255, 0} to maybe {128}, but it could b…

After drawing contours in image now i want to crop the sudoku grid but i am confuse in how to send the coordinates of grid in Nx.slice to crop image because draw contours give reference only, i also change it in tensor but it gives whole image pixels. [msg5374000099-1898] Also, i use CHAIN_AP…

For question 1, Nx.slice can only slice a rectangular area for you. To get the puzzle, you can use Evision.warpPerspective. There is an example of this function, evision/examples/warp_perspective.livemd at main · cocoa-xu/evision · GitHub . For question 2, there could be 2 possible reasons, perhap…
