Include "memory_tracker.h" in every source file where you want to track allocations.
The memory tracker header should come after all other includes.
Include -DMEMORY_DEBUG in the build to enable memory tracking.

# This is a program to filter photos with ifunny watermarks.
# I wrote this script for personal use to separate saved ifunny memes from other photos on my phone.
# The script is fully parallelized and is able to make good use of technologies like Intel
# hyperthreading because substantial program time is spent in IO. Bottleneck will be IO.
#
# Watermark false positive rate appears to be < 1/500
# Watermark false negative rate appears to be ~ 1/500
# False positive / negative rate checked with manual spot check sample size = 500.
