image - How to combine two features (two minimum distance classifiers) -

-

hello first post here,

i work on tracking objects through images without prior training. use 2 features, color of region (the ab channels of lab space) , hog. in initial experiments, found using min. distance classifier hog feature alone has advantage of low false positives fp high fn. on other hand, using min. distance classifier color alone increases tp , decreases fn results price of increasing fp.

my question, how combine 2 classifiers? know standard algorithm in unsupervised way.

i tried combine 2 features 1 feature (after normalization) hog dominates results. if weighted combined feature, results worse either of two.

the results reach till (cascade) 2 classifiers, running color first increase possibilities run hog (with threshold little bit higher used hog alone). googled topic don't have enough knowledge classification find standard methods.

thanks

Image
if set mycoolbar.fixedorder true,only grip on first band hidden. well,if use delphi 7 create vcl forms application,then put coolbar on , create 3 coolbans hold other controls,only grip , top coolbands can hidden setting mycoolbar.fixedorder:=true. i've uploaded picture make things clear. you got fixedorder property wrong. fixed property not allow bands rearranged if set true . setting property of coolbar true keep user changing bands order @ runtime, user can still move , resize bands. can give advice can do, actual solution problem, well, have wait answer. my advice use 3 coolbars in row , setting "fixedorder" property true , bandborderstyle bsnone . way grip hidden on of them. about property, it's not bug of ide, actual preference of property.

javascript - Animating array of divs; only the final element is modified -

this baffling me @ moment. i'm experienced programmer looking throw bit of surprise fiancee on countdown page our wedding. desired effect simulated confetti falling behind main page. setup follows: i have array of divs in javascript. each div absolutely positioned on page. have interval set updates every 50 or milliseconds. on each tick, run loop on array of divs, , calculations , update positions. problem problem having, however, though can see divs created, stored array, , modified (in case, each has slight randomized rotation) during initialization phase, once tick update position starts, div stored in whatever last slot of array gets position updated. tried hard-coding each div index testing purposes, strictly last element update position. upon printing current "left" , "top" style values each div before , after calculations shows value has been changed, no visible change noticeable. here's basic code: javascript var container;
