-# DP - Spájanie snímkov + úprava jasu
+# Stitching Barrel Surface Images and Correcting Their Brightness - Master's Thesis
 
-verzia opencv: 4.5.2
+
+##### Prerequisites
+OpenCV version: 4.5.2
+https://docs.opencv.org/4.x/d7/d9f/tutorial_linux_install.html
+
+C++17
+
+jsoncpp
+```sh
+sudo apt install libjsoncpp-dev
+sudo ln -s /usr/include/jsoncpp/json/ /usr/include/json
+```
+
+##### Files
+test-stitch.cpp - OpenCV tutorial file for stitching
+test-kmeans.cpp - OpenCV tutorial file for K-Means alg.
+pointbase.cpp - Structure for organizing points representing images
+test.cpp - General functionality tests - for proper function, folder containing images+json files is required on the same level as src
+makefile
+
+##### Compilation
+Compile using make
