Witryna11 kwi 2024 · Conceptually, your edges aren't sharp enough because contour detection isn't the right algorithm for the task. You're trying to segment the edges of circles (using imbinarize), but then you're doing contour detection on that, which is giving you the edges of the edges of circles.So instead of doing contour detection, you should try to … WitrynaSmooth Out Zooming Artifacts As you zoom in on an image, the pixels in the region of interest become larger and detail in the image is quickly lost. You can use image resampling to smooth out these zooming artifacts. Zoom in on the bright spot in the center of the original image.

Figure 11: Applying Canny edge detection to a collection of coins using a wide range, mid range, and tight range of thresholds. In the above figure, the top-left image is our input image of coins. Witrynaimshow()also allows you to change the upper and lower values of each axis, and the appropriate tick labels will be drawn. This feature can be used to apply physical spatial scales to the image (if you know them) rather than going purely on pixel positions, which may be less useful.
