detection

问题 I am trying to recreate Copter in visual basic, so far I have the player, roof and helicopter but I can't seem to get the game to end when the player touches the floor or roof. Sorry for posting so much, this is my first time on here and I didn't know what to paste. Any help is appreciated :D Public Class Form1 Dim pb_field As PictureBox Private Sub create_field() pb_field = New PictureBox With pb_field .Top = 20 .Left = 20 .Width = 500 .Height = 300 .BackColor = Color.Black End With Me

问题 I'm trying to make a screen locker software, that unlocks only when the correct flash drive plugged in and locks when it's unplugged. So that I have searched and found some codes that detects flash drive. It works properly when there is only one flash drive but if there are more than one flash drive and I unplugged the one without pass, my software still locks the screen. Can anyone help with it? here is my codes Imports System.Runtime.InteropServices Imports System.IO Public Class Form1

问题 Intro: I'm new to machine learning and me and a colleague have to implement an algorithm for detecting traffic lights. I downloaded a pre trained model (faster rcnn) and ran several training steps (~10000). Now when using the object detection algorithm from the tensorflow git repository several traffic lights in one area are detected. I did a little research and found the function "tf.image.non_max_suppression" but I cannot get it to work as intended (to be honest, I cannot even get it to run

问题 I am trying to scan a USB drive that is inserted into a Raspberry Pi running Windows 10 IoT Core for a specific file in a specific folder. I am currently able to detect when a USB drive is added or removed from the device using Windows.Devices.Enumeration.DeviceWatcher and can find the DeviceId using that as well. I did this using the DeviceEnumerationAndPairing demo project. I am aware that StorageDevice.FromId() would work for this usually but it seems to not agree with Windows 10 IoT Core.

问题 Anybody have any advice on how to programmatically detect if Windows Media Player is installed? I know about the registry setting look up, but don't trust it since it's more than a little misleading (uninstalled may not remove it). And I've considered just launching a video, but an error could be caused by something other than Media Player not being installed, so it's not conclusive either. Ideally, I'd prefer a solution which could be used from both my C++ application AND my NSIS installer.

问题 I'm trying to get collision detection between different materials within an scn node. I have a cube with 6 different materials/ colors and balls coming at the cube. I'd like to detect same and different colored collisions but don't know how to apply different categories to each material. import UIKit import SceneKit class GameViewController: UIViewController, SCNPhysicsContactDelegate { Can I create categories to assign to different sides of the cube later? let ballCategory = 0 let

问题 I need to know which mail clients support the "automated labeler" email address format. From research I have found only one: Gmail. They support labeled email addresses like: name+label_1@gmail.com name+label_2@gmail.com etc. The above emails are unique but reference name@gmail.com with unique labels. Follow this question and answer for more insight on this topic. Note that the "automated labeler" isn't a GMail specific feature, Gmail simply popularised it.. Other mail servers support this

问题 I am using WMI to detect a number of items about a network adapter's state. Among the things I need to find out are (a) speed and (b) duplex. I have been able to detect the speed of a network adapter by using WMI and the following Python code: from pycom.client import wmi dev_name = r"\\DEVICE\\{287EB4BB-5C2A-4108-B377-15E1D0B0E760}" query1 = """ SELECT * FROM MSNdis_EnumerateAdapter WHERE DeviceName = '%s'""" % dev_name wmi_ndis = wmi.WMI("root\\WMI") results = wmi_ndis.ExecQuery(query1)

问题 I am implementing algorithm in java which select a portion of image as marker. My problem is 1) After selecting the marker area, how do i get the specific mean value of marker color in RGB as the number of pixels with a small difference in color. 2) How can i find marker value, meaning the threshold value for the color, based on the previous marker selection. Please provide an algorithm and if posssible, an implementation in java. Thanks in advance. 回答1: I'm not sure what you tried, and where
