Today I'll show you one way to visualize the sRGB color gamut in L*a*b* space with assistance with a couple of new functions introduced last fall in the R2014b release. (I originally planned to post... read more >>

I promised earlier to post about divergent colormaps. A divergent colormap is usually constructed by concatenating two colormaps together that have different color schemes.Here is an example of a... read more >>

I hesitated for some time today about where to go next in my discussion about the new default colormap in MATLAB. I finally decided to spend a little time on the reactions so far. Those reactions... read more >>

A fascinating question came to the Image Processing Toolbox development team recently from Brett Shoelson, a MathWorks application engineer, prolific File Exchange contributor, and former MATLAB... read more >>

How can you find out what's in an image file before you read in the data? The answer is the function imfinfo. Today I want to explore the basics of using this function.The function imfinfo returns a... read more >>

Today's blog post comes from the stream of image processing questions over at MATLAB Answers.User arjun wanted to know how to remove circles from an image by specifying their center and radius.Famous... read more >>

Today's post is part of an ongoing (but long delayed) tutorial series on digital image processing using MATLAB. I'm covering topics in roughly the order used in the book Digital Image Processing Using MATLAB.... read more >>

I'm going to play a small trick on you today. Try reading in this JPEG file using imread:url = 'https://blogs.mathworks.com/images/steve/2014/peppers.jpg'; rgb = imread(url); imshow(rgb) So... read more >>

MATLAB user Meshooo asked a question on MATLAB Answers about a problem with the createMask function associated with impoly. Meshooo observed a discrepancy between the output of bwboundaries and the... read more >>

"Is there anything else you would like to tell us?"This was the question whose answer led me to revisit an old friend of mine, the roifill function. This is a function that smoothly fills a... read more >>
