Detecting Length of Segmented Image in EmguCV C# -


the requirement measure distance of canny edged images on program. specific images i'm working on human feet. have done program via matlab. wanted make standalone program via c# have link measurements in database.

to this, i'm using matlab codes algorithm emgucv c# code on vs2013.

image segmentation codes converted c# codes. on matlab "boundingbox" equivalent drawing rectangles in emgucv. got stuck.

hard-coding more complex quite straightforward. there anyway measure length of segmented image via drawing rectangle or measuring endpoints of feet itself.

here's matlab codes converted c#

 = imread('feet1.jpg'); %// pre-processing. treshold image , dilate it. level = 0.9; b = im2bw(a,level); %// detect edges f = edge(b,'canny'); figure;  imshow(f); hold on;

c#

private void opentoolstripmenuitem_click(object sender, eventargs e)         {             openfiledialog ofd = new openfiledialog();             if (ofd.showdialog()==dialogresult.ok)             {                 _imginput = new image<bgr, byte>(ofd.filename);                 imagebox1.image = _imginput;             }         } public void applycanny(double thresh=50.0, double threshlink = 20.0)     {         if (_imginput == null)         {             return;         }         image<gray, byte> _imgcanny = new image<gray, byte>(_imginput.width, _imginput.height, new gray(0));         _imgcanny = _imginput.canny(thresh, threshlink);         imagebox1.image = _imgcanny;     }

the remaining codes i'm stuck on converting:

    %draw boundaries on canny edged image k = 1:length(b),  boundary = b{k};  plot(boundary(:,2),boundary(:,1),'b','linewidth',2); end %measure boundaries measurements = regionprops(f, 'centroid', 'boundingbox'); centroid = measurements(1).centroid; bb = measurements(1).boundingbox; y1 = bb(2); % top of bounding box. y2 = bb(2)+bb(4);  % bottom of bounding box. centroidtotoe = y2 - centroid(2);

edit: adding codes

neo4j - finding mutual friends in a cypher statement starting with three or more persons -

Image
i trying build cypher statement neo4j know 2-n starting nodes name , need find node (if any) can reached of starting nodes. at first tought similar "mutual friend" situation handled (start1)-[*..2]->(main)<-[*..2]-(start2) in case have more 2 starting points around 6 know name. so puzzled how can include third, fourth , on node cypher able find commmon root amongst them. in above example neo4j website need path starting 'dilshad', 'becky' , 'cesar' check if have common friend (anders) excluding 'filipa' , 'emil' not friends of three. so far create statement programmatically looks like match (start1 {name:'person1'}), (start2 {name:'person2'}), (start3 {name: 'person3'}), (main) (start1)-[*..2]->(main) , (start2)-[*..2]->(main) , (start3)-[*..2]->(main) return distinct main but wondering if there more elegant / efficient way in cypher possibly use list of names parameter ...

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.
