Colorising Black & White Photos using Deep Learning
Previous works have used deep learning. They used regression to predict the colour of each pixel. This, however, produces fairly bland and dull results. Previous works used Mean Squared Error (MSE) as the loss function to train the model. The authors noted that MSE will try to'average' out the colors in order to get the least average error, which will result in a bland look.
