android - opencv - Detect and optimize shapes -


i have challenge have implement sample apps on android. app allows user draw shapes on screen (by finger) , optimize vertex based shapes. thinking opencv don't know function/feature can me detect shape , optimize it. need hints or recommendations.

update: user can draw type of shapes such as: circle, ellipse, rectangle, line, curve, polygon, ... think should have general algorithm kind of shapes.

thanks.

java - Multi-Label Document Classification -

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
