Began testing with an 80/20 split using my dataset. However, you can see here obviously that there are many issues with the program. Here is my new approach:
- Test out (Not completely change to) fisher chi squared weights, maybe EMD is the problem?
- Redo the dataset using three classes
- Scrap current shadow detection

Went through all of my data and sorted through images, specifically from forest8 and forest17 since those were incredibly problematic. I then collected averages for 50 images for each class from my training group for my HSV algorithm so i can start testing and creating a demo website.

created the all drives page, start looking into how to actually use react native so I can start making it for real

Created a unified system that evaluates both the color and the noise! the algorithm is complete, and the next steps are completing the implementation of other algorithms to run comparative analysis and a demo website for people to play around with the system on.

a little bit of a breakthrough with using canny instead of laplachian to look out for density of sharp edges in value differences rather than entire fluctuations! You can see in the terminal that the canopy (good) image registers a much higher canniness score than the low shrub, which has fewer and less sharp shadows. This is the direction I want to take the texture detection algorithm in, now it’s just time to integrate it into the decision making machine

the final sort. ~2200 images fully sorted into their respective categories and ready for training.

horrible day today with the sorting process. I changed the types to canopy, dry, lowShrub, and patchy, which was a small change but that meant I had to redo the sorting which was OK with me at first because these category names make more sense. then I realized that there was an issue with my google colab project where it wouldnt send the images to lowShrub folder because i had hardcoded “flat” into there which was really stupid of me so I wasted another hour there. I’m back at 1100/2200 images sorted and unfortunately it looks like I’m gonna have to finish this tomorrow.

I worked on creating some screens for logging in, migrating, and the home page for the app in figma.

I’ve been going through a new set of images and classifying them for my yolov8 model that im gonna benchmark and compare this to with the categories “canopy”, “dry”, “flat”, and “patchy”. I got 1100/2200 of those images done and uploaded to lapse.

Worked on using Earth Mover’s Distance algorithm in order to calcualte HSV color distance rather than absolute difference. EMD is the standard for these types of applications so this is a good change. I also noticed that the visualiation from last devlog didn’t load so i also uploaded that in this devlog image

began on implementing my own HSV algorithm! i’ve already had some work put into it from previous project but most of this is made by hand. Essentially, it goes through each pixel in the image using vectorization and places it on a 2D histogram. it’s 12 buckets wide for hue and 8 buckets high for saturation. I then used matplotlib in python in order to visualize the 2D histograms and then start comparing it to the reference images that the uesr inputs, although I haven’t been able to numerically compare them yet. below attached is a result and its visualization

Set up a YOLOv8 model that is fine tuned to categorize vegetation images into good, mediocre, and poor vegetation. I actually started doing the categorization for training data a while ago but all of the technical stuff began after June 1st and that time was not logged. Ive done this before so it was quite easy, and its classifying well!
