Why we use only Convolutional Neural Network for the Image recognition?

Ans. Convolutional Neural Network is developed from the inspiration of the visual cortex in Human Brain. CNN are the complex feed forward Neural Network which is used for Image recognition for its high accuracy. The CNN follows a hierarchical model which works on building a network, like a funnel, and finally gives out a fully-connected layer where all the neurons are connected to each other and the output is processed.
