Digital Image Processing Using MATLAB offers a balanced treatment of image processing fundamentals and the software principles used in their implementation. The book integrates material from the 4th edition of Digital Image Processing by Gonzalez and Woods, the leading textbook in the field, and Image Processing Toolbox. Image Processing Toolbox provides a stable, well-supported software environment for addressing a broad range of applications in digital image processing. A unique feature of the book is its emphasis on showing how to enhance these tools by developing new code. This is important in image processing, a field that generally requires extensive experimental work in order to arrive at suitable application solutions.
