Is deep learning is for images?

Yes you can use deep learning techniques to process non-image data. However, other model classes are still very competitive with neural networks outside of signal-processing and related tasks. To use deep learning approaches on non-signal/non-sequence data, typically you use a simple feed-forward multi-layer network.

Is image recognition machine learning?

The images from the created dataset are fed into a neural network algorithm. This is the deep or machine learning aspect of creating an image recognition model. The training of an image recognition algorithm makes it possible for convolutional neural networks image recognition to identify specific classes.

How does CNN detect objects?

The faster region convolutional neural network [15] is another state-of-the-art CNN-based deep learning object detection approach. In this architecture, the network takes the provided input image into a convolutional network which provides a convolutional feature map.
