WebApr 11, 2024 · The proposed ANN based method for image resizing consists of the following steps (Fig. 1). First of all, the camera captures the original image. Then, it is resizing using the interpolation method. After that, the JPEG compression process takes place. The compressed image is transmitted to the receiver using a radio module. WebDec 9, 2024 · Hello all, I would like to plot the Probability Density Function of the curvature values of a list of 2D image. Basically I would like to apply the following formula for the curvature: k = (x' (s)y'' (s) - x'' (s)y' (s)) / (x' (s)^2 + y' (s)^2)^2/3. where x and y are the transversal and longitudinal coordinates, s is the arc length of my edge ...
