Hue shifts near the L*=0 axis 7

At the European Colour in Graphics, Imaging, and Vision conference today, I took a tutorial called "Transforms for Colour and Spectral Reproduction." Mitch Rosen of the Munsell Color Science ... read more >>

European colour

Next week I'll be in the UK. On Monday I'll be attending the International Color Consortium's DevCon 2006 at the University of Leeds. The MathWorks is a member of the ICC and is a sponsor of... read more >>

Spatial transformations: findbounds 12

I've written previously about how Image Processing Toolbox uses inverse mapping to implement spatial transforms. In this method, you set up a grid in output space. For each pixel in the... read more >>

Determining point positions in MRI peg phantom 38

Blog reader Jonathan from St. Jude Children's Research Hospital sent me an image derived from an MRI peg phantom:bw =... read more >>

Batch processing 72

23-Jun-2015 update: See the new Image Batch Processor App (added to R2015a) and my blog post about it. A couple of months ago I was working with a bunch of pictures I had taken at... read more >>

Cell segmentation 119

Blog reader Ramiro Massol asked for advice on segmenting his cell images, so I gave it a try. I'm not a microscopy expert, though, and I invite readers who have better suggestions than... read more >>

A little deadline pressure

In a recent comment, blog reader Ramiro asks where I've been for the last couple of weeks. Well, I've been right here at my desk, working hard in advance of critical R2006b development deadlines.... read more >>

Spatial transformations: Where is the output image? 7

I wrote previously that most spatial image transformation implementations use inverse mapping. The Image Processing Toolbox function imtransform is implementated using this technique. Here's... read more >>

A Lab-based uniform color scale 40

DSP Tips & Tricks One of my favorite professional publications is IEEE Signal Processing Magazine. It has a regular feature called "DSP Tips & Tricks." In the January... read more >>

Spatial transformations: Inverse mapping 19

I wrote last week about the forward mapping method of spatially transforming images. Because of the disadvantages of the forward mapping method, most of the practical implementations use a... read more >>
