Image-Conversions

This repository had several functions and their working code for several Image Conversions as follows:

• Color to Binary Conversion
• Image Interpolation

Sample Images Folder - 'Image_Samples' click here

Color to Grayscale Conversion:

The RBG image consists of 3 bands 'Red', 'Green' and 'Blue'. This three bands can be combined to get a single grayscale band according the formula given ITU Recommendation (Rec. 601) as

$$ Y = (0.299 \times R) + (0.587 \times G) + (0.114 \times B) $$
