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 ... 続きを読む >>

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... 続きを読む >>

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... 続きを読む >>

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... 続きを読む >>

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... 続きを読む >>

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.... 続きを読む >>

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... 続きを読む >>

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... 続きを読む >>

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... 続きを読む >>
