+# Neon Effect Filter
+
+Converting an image into an neon effect filtered image using some of the python libraries.
+
+## Libraries used
+Firstly import the following python libraries 
+* OpenCv
+* Os
+* Matplotlib 
+* Numpy
+
+Taking path of the image/Real image as input using os and finally reading it using cv2
+
+## Detailed explanation of the method used
+
+* Imported the required libraries ( Numpy, Matplotlib, OpenCv, Os)
+* Read the input path of the image using Cv2 library
+* Used Bilateral Filter
+* Followed by Median Blur
+* Followed by Adaptive Threshold
+* Followed by Bitwise "and" between original image and edge image
+* And at last used Bitwise "xor" between orginal and output of the above "bitwise and image"
+* Finally converted the image into "Neon Effect Filtered" image
