Webb25 jan. 2024 · One way to get rid of the noise on the image, is by applying Gaussian blur to smooth it. To do so, image convolution technique is applied with a Gaussian Kernel (3x3, 5x5, 7x7 etc…). The kernel size depends on the expected blurring effect. Basically, the smallest the kernel, the less visible is the blur.

The active contour model is a method to fit open or closed splines to lines or edges in an image [ 1]. It works by minimising an energy that is in part defined by the image and part by the spline’s shape: length and smoothness. The minimization is done implicitly in the shape energy and explicitly in the image energy. regency new homes memphisWebb9 feb. 2015 · Step 1: Detect and find contours in your image. Step 2: Loop over contours individually. Step 3: Determine if the contour is “bad” and should be removed according to some criterion. Step 4: Accumulate a mask of “bad” contours to be removed.
