R Image Processing and Image Clustering: Simple Computer Vision in R
Use the R programming language to generate and process graphics, images and pictures! Cluster images from the Yale face database! Perform statistical tests and run machine learning algorithms on images to identify patterns and clusters. This video is part of a series dedicated to statistical programming in R and RStudio. We use the "magick" R package for image processing, and the "caret" R package for the statistical analysis. We run principal component analysis (PCA) on the image data, and random forest for image classification.

Why don't you leave the scripts free to practice and enjoy the exercise you just did?
This is good stuff, sad you seem to have stopped uploading! Consider making more!
in the case of monte carlo simulation with poisson distribution why do i have to put this code is rpois(M,n*theta0) , M*n, or n*theta0?
Big thanks. It is easy to understand and quite helpful.
What if the images are of different sizes?
Please please please just add the code somewhere online, so that we don't have to type off everything from our screen. nice video though!
Very informative lecture for MC integration 👍. Thank you so much for this video.
Great work!! Keep it up
Thank you for the tutorial, can you show me how the pixel by pixel classification is done for the following input data, 1. I have NDVI, EVI ,SAVI and SAMI image for my basin and I want to make pixel by pixel classification to 4 clusters so, if you are familiar for this help me
This is superb! We need more examples like this demonstrating the use of R.
Amazing, please continue making videos. Edit: I looked at your tutorials on your website, you are extremely talented. I never learned so much from a single source. Thanks for making these.
Why so few views ?? Amazing !!! :)
Thank you so much for these wisdom nutshell videos shared! 216 is the half of 432 // 432x432=c in miles per second. // 216*864=c // This are glimpses of the investigation to publish soon! Cheers from Mexico! <3
Thank u sir
Thank you for the video! Can you please explain the step as.numeric(current_image[[1]][1, ,]), what does Index [1, , ] do? I cant find an explanation anywhere.
Thank you so much, it's quite clear.😃
Upload more! This was great!
thanks for your sharing...great content. can this technique be applied for UAV imagery?
Welp, i cant get the images to load propperly. FML.
thank for this tutorial
Very precious! Love this video.
Hello, is there a command where you put a function (example: f(x) ) and R shows you the indefinite integration? I know how to see result of a definite integration, my problem is with indefinite‘s and for example with derivation you can put in a function and it shows you the derivate, I wonder if there’s a similar way but for integration. Please, let me know, thanks a lot!
Thank you so much
I get an error "number of columns of result is not a multiple of vector length" What to do if the images are not in the same size?
thanks for saying it will get better in time, you da real MVP
Very clear and very neat. It would be nice to visualize the circle.
amazing video, thanks
Thank you for the tutorial. Could you please upload a video for fMRI data simulation using neuRosim in R..
Your content is great, thank you!
Thanks - another wonderful video.
Very nice!
amazing thank you so much
Hi, could you please make a video teaching how to do Monte Carlo simulation to find the mean and confidence interval? I have some observations of fishing net sizes (27) and I would like to do MC simulation (ex. using 1000 interactions) to estimate a mean value and confidence interval that I can use to estimate the swept area by these nets. Using a fixed boat speed and haul time, I would like to use the mean net size (and intervals) to calculate swept area scenarios. Here are the net size observations: c(20.6, 16.4, 17.5, 23.2, 23.0, 18.6, 20.6, 13.7, 23.2, 27.4, 19.4, 19.4, 18.5, 17.5, 24.8, 26.0, 17.4, 21.9, 26.7, 24.3, 26.6, 24.5, 24.7, 22.2, 20.0, 20.8, 23.9) Any help is very welcome. Cheers
Can you do a Monte Carlo or bootstraping video to estimate a mean from 10 values?
Thanks much appreciated - Great presentation - clear, concise and excellent pace and timbre :). Please sir - may we have some more!
Very helpful Please add more videos
Nice! Good basic introduction to monte carlo estimation in R.
