Feature Extraction in Machine Learning

During the Machine Learning life cycle process, you will often need to figure out how will you extract the features from the text data or from the image datasets or from the sensors data etc. ? or how will you create the new features from the existing features ? if so, then you have to perform the feature extraction to solve all the above issues in machine learning life cycle projects , here I am going to cover all the feature extraction steps in more details.

sir by using ML we can convert any image to pixels and identify the features of image..is it possible to identify eye problems through such features
