opencv - How Can I Detect Any Object from Video Camera in IOS? -


i developing application identify object real world object. possible identify object video camera? on words using opencv library identify object. recording video not anything. poor ar. please suggest me have identifying real world object if possible.

step 1: follow this setup opencv camera

step 2: add code processimage delegate

- (void)processimage:(cv::mat&)image {       //process here       cv::cvtcolor(image, img, cv::color_bgra2rgb);       int fixedwidth = 270;      cv::resize(img, img, cv::size(fixedwidth,(int)((fixedwidth*1.0f)*   (image.rows/(image.cols*1.0f)))),cv::inter_nearest);      //update model     bg_model->apply(img, fgmask, update_bg_model ? -1 : 0);      gaussianblur(fgmask, fgmask, cv::size(7, 7), 2.5, 2.5);     threshold(fgmask, fgmask, 10, 255, cv::thresh_binary);      image = cv::scalar::all(0);     img.copyto(image, fgmask); }

you'll need declare following global variable 

cv::mat img, fgmask; cv::ptr<cv::backgroundsubtractor> bg_model; bool update_bg_model;

where, img <- smaller image fgmask <- mask denotes motion happening update_bg_model <- if want fixed background;

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
