i have detect eyes picture , after need coordinates them. http://damngoodcup.com/wp-content/uploads/scream-mask.jpg i have used opencv, , following command: eyes_cascade.detectmultiscale(frame_gray, eyes, 1.1, 2, 0 | cv_haar_scale_image, size(30, 30)); on other pictures (for eg.: on selfie) it's working, "scream face" it's useless. is there way find eyes on picture? (using opencv not important if there easier solution) haar classifier provided opencv not work image (face, eyes, etc), because differs positive training data, limited humans' faces. example, humans' eyes have different features extracted haar features "eyes" in image you've provided. if detect eye-like region in image haar cascade, have train own yourself. don't think can find kind of such trained classifier.

the idiom dealing optionals in swift seems excessively verbose, if want provide default value in case it's nil: if let value = optionalvalue { // 'value' } else { // same thing default value } which involves needlessly duplicating code, or var unwrappedvalue if let value = optionalvalue { unwrappedvalue = value } else { unwrappedvalue = defaultvalue } which requires unwrappedvalue not constant. scala's option monad (which same idea swift's optional) has method getorelse purpose: val myvalue = optionalvalue.getorelse(defaultvalue) am missing something? swift have compact way of doing already? or, failing that, possible define getorelse in extension optional? update apple has added coalescing operator: var unwrappedvalue = optionalvalue ?? defaultvalue the ternary operator friend in case var unwrappedvalue = optionalvalue ? optionalvalue! : defaultvalue you provide own extension optional enum: extension optio...

how find median of list in python? list can of size , numbers not guaranteed in particular order. if list contains number of elements, function should return average of middle two. here examples (sorted display purposes): median([1]) == 1 median([1, 1]) == 1 median([1, 1, 2, 4]) == 1.5 median([0, 2, 5, 6, 8, 9, 9]) == 6 median([0, 0, 0, 0, 4, 4, 6, 8]) == 2 python 3.4 has statistics.median : return median (middle value) of numeric data. when number of data points odd, return middle data point. when number of data points even, median interpolated taking average of 2 middle values: >>> median([1, 3, 5]) 3 >>> median([1, 3, 5, 7]) 4.0 usage: import statistics items = [1, 2, 3, 6, 8] statistics.median(items) #>>> 3 it's pretty careful types, too: statistics.median(map(float, items)) #>>> 3.0 decimal import decimal statistics.median(map(decimal, items)) #>>> decimal('3')

does know why in example the inner <div> displayed vertically instead of horizontally? i use chrome element inspect can see huge margin area on right of each <div> , without margin value. found example could answer question, too. in case needs it. it happens because using block layout each inner div ( display:block default div elements). instead should use (for example ) display:inline-block , reduce width (to 33% in example) adds pixels spacing between 3 inner divs : .cols_section > div{ display:inline-block; } example another option use table layout, don't have change width each inner div: .cols_section { display:table; width:100%; } .cols_section > div{ display:table-cell; } example

so far understand: sender starts handshake server. server generates pair of public , private key using asymmetric encryption , re-encrypt public key alone using symmetric encryption. , passes public key sender. sender encrypt message using public key , sends encrypted message server. server decrypt message using symmetric encryption , decrypt message again using private key. is right way how ssl encryption works?? please correct me. sender starts handshake server. client starts handshake server. server generates pair of public , private key using asymmetric encryption , re-encrypt public key alone using symmetric encryption. no. and passes public key sender. no. sends certificate client , start secret-key negotiation. sender encrypt message using public key no. uses symmetric session key negotiated during handshake. and sends encrypted message server. yes. server decrypt message using symmetric encryption yes. a...

in program i'm working on, particular operation not going bottleneck, did me thinking. answers questions such this one , this one i've learned 2 ways (efficiently) set elements of array 0 in c: double myarray[3]; static const double zeroes[3] = {0}; memcpy(myarray, zeroes, sizeof(zeroes)); and double myarray[3]; memset(myarray, 0, numberofelementsinmyarray * sizeof(myarray[0])); before move onto real question: i'm not entirely sure based on the information i've read, assume method would, @ least in principle, fill array int zeroes (well, unsigned char 's these seem equivalent ). correct? if so, explicit conversion of int zeroes double zeroes necessary or done implicitly if myarray declared array of double 's? anyway, real question this: if array isn't big @ (like myarray i've declared above), either of these methods still preferred on little loop? if have few arrays of same small size need assigned zeroes? if commented properly, thi...
