dears 1-i know point class regarding 2 channel integer value coordinates(points): matofpoint vector of integer points. same keypoint class? know class containing salient points.is true @ them 2 channel float value coordinates(points)? @ lines below: keypoint test; test= new float[]{x,y}; i wrote them see if interpretation regarding keypoint valid. please validate this. 2-what dmatch match.trainidx? mean trainidx? peace keypoint stores salient points description. stores x, y, angle, size etc. see http://docs.opencv.org/java/2.4.2/org/opencv/features2d/keypoint.html correct way manually initialize in java be: keypoint test = new keypoint(x, y, size); or list of keypoints image : mat srcimage; matofkeypoint keypoints; mat descriptors; descriptorextractor descexctractor = descriptorextractor.create(descriptorextractor.sift); descexctractor.compute(srcimage, keypoints, descexctractor); keypoint[] keypointsarray = keypoints.toarray() dmatch constains descri...

i have situation manipulation events emanating offscreen (think bezel of surface pro) not being registered when app in fullscreen mode. however, registering expected when application "maximized" (i put in quotes because know it's no longer officially "thing" maximized). to reproduce, create blank application , add code @ end of post. swipe top down, , notice absence of manipulation events being fired. click exit full screen button maximize button , repeat experiment, , see manipulation events fire. it important start dragging offscreen. is design? there gotcha i'm not aware of? bug? the following xaml file: <page x:class="edgeswipedetect.mainpage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:edgeswipedetect" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas...

i designing custom ble device protocol. device 1 of - scales, blood pressure monitor, fitness band . the protocol defines collection procedure android/ios app ( collector ) use collect sensor data 1 of these devices. we can assume collector present 50% of time , scanning air broadcasted device connect , collect data it my question is: effective way of making device connectable, battery power in mind? my current approach: device connectable, if (a) has unsent measurements user, (b) user turned on (by stepping on scales, pushing button or whatever) in case (b) device broadcasts e.g. each 1 seconds , available connected collector in case (a) device broadcasts e.g. each 5 seconds , available connected collector as conditions (a)/(b) not apply, device goes sleeping mode - not broadcasting anything. is effective approach means of energy consumption? or there better practices accomplish "device visibility" ? p.s. not find better resource asking that,...
