What are some algorithms to segment character in a word picture

Question

Above is the picture, I want to segment character in TEST to 4 separated images, each contains T,E,S,T respectively and then use CNN to recognize each character. How many algorithms could help this? Could I use RNN with LSTM to do it? Because I prefer neural network but if there is any easier algorithm, please indicate. Thank you so much.

在英语上，所有字母都是连续区域，因此您需要进行二值化并选择（足够大，但不要太大）连续区域。
