It seems that in some parts of your videos, the screen would black out for a few seconds before it comes back on.

hello, first of all thanks for this intresting set of videos, ma'am can you please tell how to do this for a dataset of images and store the results. Thanks.
@youngresearcher.
@youngresearcher. 9 лет назад
u can open the images using dir() function which would specify location of datapath of the dataset. Am about to make a video on face identification from a dataset which would open images and do operations on them. stay tuned..

@youngresearcher.
@youngresearcher. 10 лет назад
u can read any image with the proper path specified or else load the image into ur work directory to read it directly..u can also add the path to the dir to read without specifying the location

maam can you explain me what exactly the function of "colormap" and why isn't it applying here ?
@youngresearcher.
@youngresearcher. 10 лет назад
colormap is a matrix with 3 columns and no. of rows according to the number of colors available in that colormap. Hence,each row of the matrix defines the intensity in R,G,B terms. It maps to colors in the palette of the colormap used. There are number of colormap options such as jet, spring. autumn, cool etc. which show the image according to the palette.

U probably don't have the IPT in ur matlab. verify with typing 'ver' on the prompt.
