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?

    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?

    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!

    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

  • @haraldurkarlsson1147

    This is superb! We need more examples like this demonstrating the use of R.

    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!

    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
