The book "Tasvirlarni tanish tizimlari" by Sanoyev Jahongir focuses on image preprocessing techniques for improving quality in analyzing and teaching machines about images. It covers various stages like resizing, reducing noise through filters, balancing brightness, and enhancing contrast. Normalizing data is crucial, with pixel values typically ranging from 0 to 1. Statistics show that image preprocessing can increase accuracy by 20-30%. The success of machine learning algorithms often depends on correctly preprocessed data
