Today I went through the material for Monday’s third lecture and tutorial on image processing. It’s about image segmentation and morphological operations (such as the titular erosion and dilation). I know about this stuff and how it works, but I’ve never actually done work with it or implemented it, which is what I have to teach in the tutorial session on Monday. So I worked through the exercises and got familiar with how to do them all in Matlab.
There was also another big walk with my wife and Scully today. We have a new favourite route, out along the peninsula west of us, and along a bushwalk track by the harbour shore, which emerges near streets at a small grassy area, which is quiet and where we can get Scully to run around chasing a ball for a while. It’s near the panoramic photos I posted in this entry a week ago.
COVID news was very bad today, with a new record high 466 cases in New South Wales. This has finally prompted the state government to strengthen the current lockdown restrictions, introducing them across the whole state, and reducing the distance you can travel from home from 10 km to 5 km. There’s a range of additional restrictions and removal of exceptions to get people moving around less as well. If only they’d done this 8 weeks ago when this outbreak began, we wouldn’t be in this current mess now.
