I have two similar images in which paraboloid and its contours are drawn. What I've ever tried is in the following code that is very different from the figure. \documentclass{standalone} \usepackage{tikz, tikz-3dplot} \usetikzlibrary{arrows.meta} \tikzset{reverseclip/.style={insert path=...
contours,hierarchy = cv.findContours(thresh,2,1) cnt = contours[0] hull = cv.convexHull(cnt,returnPoints = False) defects = cv.convexityDefects(cnt,hull) for i in range(defects.shape[0]): s,e,f,d = defects[i,0] start = tuple(cnt[s][0]) ...

b. the sum or type of such contours or marks, characteristic of a style or design: the line of a draughtsman; the line of a building. 11. anything long, flexible, and thin, such as a wire or string: a washing line; a fishing line. 12. (Telecommunications) a telephone connection...
I'm a beginner with OpenCV, I stumbled with a problem to draw 4 point contours around document image, I followed this tutorial and this example from StackOverflow for OpenCV.js Getting the following error: BindingError {name: "BindingError", message: "Cannot pass "[object Object]" as a ...
Sketch a contour diagram for f(x, y) = x^2 - 2y^2 with three labeled contours. Using only your brain, draw a contour map for the function z = f(x, y) = \frac{y}{x^2 + 1}. Show level curves for z-levels of -2, -1, -\frac{1}{2}, 0, ...
