I've written previously about how imtransform uses inverse mapping to compute the input-space location corresponding to each output pixel. I've also written about how imtransform uses the... 更多内容 >>

I regularly receive blog comments and direct e-mail asking for help with writing image processing GUIs in MATLAB. That's way beyond the scope of this blog, and I'm afraid I don't have time to... 更多内容 >>

I saw an interesting MATLAB based image processing application on a melanoma skin cancer blog recently. The example, including code, shows how the lesions are segmented, traced, and measured. Several... 更多内容 >>

Recently, our application support engineers gave a series of presentations to development groups. These presentations summarized calls received by tech support about different products. I thought... 更多内容 >>

The last time I wrote about spatial transformations, I explained that imtransform uses the function findbounds to locate the transformed image in output space. By default, imtransform computes... 更多内容 >>

A customer asked me last week how to do multidimensional interpolation with integer inputs. The MATLAB function interpn supports only double- and single-precision inputs. It's possible to do... 更多内容 >>

More bits and pieces from CGIV today, typed in while watching England and Sweden battle it out on the telly... it's currently 1-1. I saw a poster this morning describing how color... 更多内容 >>

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 ... 更多内容 >>

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... 更多内容 >>

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... 更多内容 >>
