 # Image Compression
 
 Python code for developing a system to compress images in order to achieve uninterrupted frames.
+
+The approach revolves around predicting a pixel based on the surrounding 4 pixels on the top and left.
+The process is thought of like a cathode ray TV, processing each row one pixel at a time. Therefore
+the 3 pixels above any nonboundary pixel and the one to the left have already been read. The goal is to then
+interpolate the next point and record if there is any difference between the predicted and the actual.
+
+Encoding_decoding contains the main body of code, while compression_benchmark.ipynb contains some test code
+for already produced methods of compression.
+
+The current status is that the inhouse compression works better as per its own method of checking the ratio.
+
+TODO: Update how it calculates compression by actual filesize instead of in python calculations
