my program's purpose take 2 images , decide how similar are. im not talking here identical, similarity. example, if take 2 screenshots of 2 different pages of same website, theme colors similar , therefor want program declare similar. my problem starts when both images have white background pretty takes on histogram calculation (over 30% of image white , rest distributed). in case, cv2.comparehist (using correlation method, works other cases) gives bad results, is, grade high though different. i have thought taking white (255) off histogram before comparing, requires me calculate histogram 256 bins, not when want check similarity (i thought using 32 or 64 bins best) unfortunately cant add images im working due legal reasons if can idea, or code solves grateful thank much you can remove white color, rebin histogra , compare: compute histrogram 256 bins. remove white bin (or make zero). regroup bins have 64 bins adding values of 4 consecutive bins. pe...

there's been change in swift 3 xcode 8 beta 6 , i'm not able declare operator power did before: infix operator ^^ { } public func ^^ (radix: double, power: double) -> double { return pow((radix), (power)) } i've read bit , there's new change been introduced in xcode 8 beta 6 from i'm guessing have declare precedence group , use operator this: precedencegroup exponentiativeprecedence {} infix operator ^^: exponentiativeprecedence public func ^^ (radix: double, power: double) -> double { return pow((radix), (power)) } am going in right direction make work? should put inside {} of precedence group? my final aim able make power operations simple operator in swift, e.g.: 10 ^^ -12 10 ^^ -24 your code compiles , runs – don't need define precedence relationship or associativity if you're using operator in isolation, such in example gave: 10 ^^ -12 10 ^^ -24 however, if want work other operators, chaining multiple expon...

i think analyzer should apply both indexing , search processes, correct? if true, why document fields still have uppercase characters after using lowercasefilterfactory filter in analyzer? i use luke check document fields. here related code. @indexed @analyzerdef(name = "remarksanalyzer", tokenizer = @tokenizerdef(factory = standardtokenizerfactory.class) , filters = { @tokenfilterdef(factory = lowercasefilterfactory.class), @tokenfilterdef(factory = snowballporterfilterfactory.class, params = { @parameter(name = "language", value = "english") }) }) public class book { ... @field(store = store.yes) @analyzer(definition = "remarksanalyzer") private string remarks; ... } did try search on index lowercased words? i'm pretty sure work. the fact is, if use store=store.yes, store unanalyzed string in index , analyzed tokens. might allow use highlighter instance: highlighted s...
