Integrate Canny with Tableau

To start off, I will be comparing and contrasting Canny and Tableau. The first step to doing this is to understand what exactly a Canny edge detector is and how it works. A Canny edge detector is an algorithm to detect edges in an image. It was built in 1986 by John F. Canny. The process of detection works by first taking the pixels of the image and then applying a Gaussian blur function to them. After this is done, the edge detection centers on finding the points where the best change of intensity occurs. Once these points are found, they are found at the area of lowest intensity in the image. The final step in the process is to find lines that connect pairs of points.

After understanding what a Canny edge detector is, we can now move on to integrating it with Tableau. The first step is to create a data source for the Canny edge detector. In order to do this, you have to. “Create a new data source by clicking the Data Source tab (icon. on the left side of your workbook canvas.” (Tableau, Inc.. This data source is called Canny Edge Detection . Now that it has been created, there are two things that need to be done. “Editing the Data Source Properties” and “Editing the Data Source Settings.” To edit the properties, you must. “Click on the data source name in the data pane above your worksheet, and then click Edit in the drop-down menu.”(Tableau, Inc.. When editing the settings, you must. “Open Data Source Settings by clicking the Edit button next to Data Source in your workbook’s Data pane.”(Tableau, Inc.)

In conclusion, we learned that a Canny edge detector detects edges and that a Canny edge detector can be integrated into Tableau.
