Interpolating along the 2-D image slices

阅读更多关于 Interpolating along the 2-D image slices

问题 I have a set of 100 2-D image slices of the same size. I have used MATLAB to stack them to create a volumetric data. While the size of the 2-D slices is 480x488 pixels, the direction in which the images are stacked is not wide enough to visualize the volume in different orientation when projected. I need to interpolate along the slices to increase the size for visualization. Can somebody please give me an idea or tip about how to do it? Edit: Anotated projected microscopy-images The figure 1

how to use black-and-white fill patterns instead of color coding on Calendar Heatmap

I'm using Paul Bleicher 's Calendar Heatmap to visualize some events over time and I'm interested to add black-and-white fill patterns instead of (or on top of) the color coding to increase the readability of the Calendar Heatmap when printed in black and white. Here is an example of the Calendar Heatmap look in color, and here is how it look in black and white, it gets very difficult to distinguish between the individual levels in black and white. Is there an easy way to get R to add some kind of patten to the 6 levels instead of color? Code to reproduce the Calendar Heatmap in color. source(
