| Screencap of the scanner log! |
Here is some of the improved areas of the new scanner:
- The new scanner has massive speed (like 100 times?) improvement. It is blazing fast, each image recognition (and we have about 60ish images to scan) cycle only takes an average of 5~10 ms on a modern CPU with a single thread. Even when we take into account of the whole cycle including the screen capture, HearthTracker still able process about 30~ frames per second. All that done without using any IF-ELSE conditions to filter images. Actual implementation will be even faster because we can reduce the images needed to be scanned by filtering them with IF-ELSE conditions.
- Much lower CPU and memory footprint. it takes only about 1~5% CPU usage on maximum scanning speed and about 80ish MB of maximum memory usage. Actual usage might be even lower for the same reason above.
- Improved on screen capture speed - it is like 10 times faster now.
- It works on multi-monitor setup without using any workaround!
What all of that means? It means HearthTracker will be able to scan faster than our human eyes can see the images. It means HearthTracker will hardly miss anything. It means HearthTracker will track A LOT more things. For starters, it will be able to track Arena Draft soon which is one of the reason that motivated me to design the scan engine.
Stay tuned for the new and improved scan engine!
