Hello everyone
I am using matlab (2016 b) data brush to brush part of data from a picture I2, but it's extremely slow. Please help or give some suggestion. Greatly appreciate it.
I2 is 282 by 282 matrix. It's quite easy to show this figure with imshow(I2), however, matlab built-in brush doesn't work on the figure generated by imshow.
Then I made little change and used scatter to plot this image as the following:
[x,y,z]=find(I2);
scatter(x,y,z)
Now matlab built-in brush works on figure generated by scatter, however, it's extremely slow when brushing data on the figure.
Could someone explain why it's like this? Is there a better way to brush some data from I2?
Thank you very much
