matlab - Would Richardson–Lucy deconvolution work for recovering the latent kernel? -


i aware richardson–lucy deconvolution recovering latent image, suppose have noisy image , original image. can find kernel caused transformation?

below matlab code richardson-lucy deconvolution , wondering if easy modify , make recover kernel instead of latent image. thoughts change convolution options valid output represent kernel, think?

function latent_est = rl_deconvolution(observed, psf, iterations)     % utilise conv2 function must make sure inputs double     observed = double(observed);     psf      = double(psf);     % initial estimate arbitrary - uniform 50% grey works fine     latent_est = 0.5*ones(size(observed));     % create inverse psf     psf_hat = psf(end:-1:1,end:-1:1);     % iterate towards ml estimate latent image     i= 1:iterations         est_conv      = conv2(latent_est,psf,'same');         relative_blur = observed./est_conv;         error_est     = conv2(relative_blur,psf_hat,'same');          latent_est    = latent_est.* error_est;     end

thanks in advance.

this simple problem. convolution commutative. hence, don't need change implementation of rl deconvolution obtain psf, can call follows:

psf = rl_deconvolution(observed, latent_est, iterations)

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
