问题 I'm making an app for iPhone in Xcode, and It requires a box to follow my finger only on the X axis. I couldn't find any solution online to this, and my coding knowledge isn't that great. I've been trying to use touchesBegan and touchesMoved . Could someone please write me up some code please? 回答1: First you need the UIGestureRecognizerDelegate on your ViewController.h file: @interface ViewController : UIViewController <UIGestureRecognizerDelegate> @end Then you declare an UIImageView on your

Automatic tracking algorithm

会有一股神秘感。 提交于 2020-01-03 08:41:36
问题 I'm trying to write a simple tracking routine to track some points on a movie. Essentially I have a series of 100-frames-long movies, showing some bright spots on dark background. I have ~100-150 spots per frame, and they move over the course of the movie. I would like to track them, so I'm looking for some efficient (but possibly not overkilling to implement) routine to do that. A few more infos: the spots are a few (es. 5x5) pixels in size the movement are not big. A spot generally does not

问题 I am trying to integrate a tracking code in Woocommerce Thankyou page. I found just the order id to fill it out. But I don't know how to complete this for order items data. Here is my actual code: <script type="text/javascript"> ADMITAD = window.ADMITAD || {}; ADMITAD.Invoice = ADMITAD.Invoice || {}; ADMITAD.Invoice.broker = "adm"; // deduplication parameter (for Admitad by default) ADMITAD.Invoice.category = "1"; // action code (defined during integration) var orderedItem = []; // temporary

问题 I am new to Wordpress development and am trying to install a traffic junky tracking code on the thankyou.php page. My attempt has failed so far and I think it boils down to not understanding PHP well enough.

Vehicle segmentation and tracking

匆匆过客 提交于 2020-01-01 06:08:48
问题 I've been working on a project for some time, to detect and track (moving) vehicles in video captured from UAV's, currently I am using an SVM trained on bag-of-feature representations of local features extracted from vehicle and background images. I am then using a sliding window detection approach to try and localise vehicles in the images, which I would then like to track. The problem is that this approach is far to slow and my detector isn't as reliable as I would like so I'm getting quite

Android & OpenCV: Homography to Camera Pose considering Camera Intrinsics and Backprojection

我的未来我决定 提交于 2020-01-01 05:31:13
问题 Libs: OpenCV Target: Android (OpenCV4Android) I try to compute the Homography of a world plane (e.g. monitor screen) to get the camera pose, transform it and reproject the points back for tracking tasks. I'm using OpenCVs findHomography() / getPerspectiveTransform() to get the homography. The reprojection of the points using perspectiveTransform() (as explained here: http://docs.opencv.org/doc/tutorials/features2d/feature_homography/feature_homography.html) which works pretty well.

WooCommerce Conversion Tracking Script for two Pixel

问题 I want to promote my products by some affiliate networks. Do only thing you have to do, is to go into the function.php file and add this script with the pixel. With this script the tracking of the amount value works fine. This script works only for one network and if you are the only vendor. add_action( 'woocommerce_thankyou', 'my_custom_tracking' ); function my_custom_tracking( $order_id ) { $order = new WC_Order( $order_id ); $total = $order->get_subtotal(); $id = str_replace('#', '',

Gmail blocking pixel tracking / 1x1 pixel since today morning

问题 I was implementing pixel tracking for a gmail web service, but since today google has changed the gmail client to proxy linked images ! Is there any work around, as the proxy is giving my server a fake/masked ip and location? 回答1: This is true. gmail has been proxying all user content via it thus showing Mountain View,CA as its REMOTE_ADDR . This is true only for gmail clients. The same logic has not been working on Gmail via outlook or any other mail client. Most email tracking companies

Blob tracking algorithm

二次信任 提交于 2019-12-30 03:20:21
问题 I'm trying to create simple blob tracking using OpenCV. I have detected the blobs using findcontours. I would like to give those blobs a constant ID. I have collected a list of blobs in the previous frame and the current frame. Then I took the distance between each blob in the previous frame and the current frame. I would like to know what else is needed to track the blobs and give them an ID. I just took the distance between previous and current frame blobs, but how can I assign the blobs a
