Kinect depth conversion from mm to pixels

由 孤人 提交于 2020-01-03 05:16:14
问题 Does anybody knows how many pixels correspond for each millimeter of depth value in images taken from kinect for xbox360? I'm using the standard resolution and settings... Thanks! 回答1: 1 pixel corresponds to a number of millimiters that depends on the depth value of that pixels (i.e. its level of gray). The simplest way you can get the distance between two pixels in a depth image is to convert those pixels (which are expressed in Depth Space ) in real world coordinates (i.e. in Skeleton Space

问题 I am using the following css on my meter-bars but somehow the styling does not work on safari (see below screenshots). I am pretty new to css and copied below css.

How can I implement a volume meter for a song currently playing? (iPhone OS 3.1.3)

由 倾然丶 夕夏残阳落幕 提交于 2019-12-13 02:34:35
问题 I'm very new to core audio and I just would like some help in coding up a little volume meter for whatever's being outputted through headphones or built-in speaker, like a dB meter. I have the following code, and have been trying to go through the apple source project "SpeakHere", but it's a nightmare trying to go through all that, without knowing how it works first... Could anyone shed some light? Here's the code I have so far... (void)displayWaveForm { while (musicIsPlaying == YES { NSLog(@

how to change <meter> values?

由 折月煮酒 提交于 2019-12-12 13:43:37
问题 I'm a beginner at HTML, and while learning about HTML5 I've found a cool tool, the <meter> . However, it won't update; it's there as a static value! My question is simple: how do I use the length of a <textarea> to change the color of <meter> , so that the user will, for example, see red when he reaches 160 characters (the maximum value)? In other words, count the <textarea> characters, and send them to the value of the meter tag. 回答1: Note that not all browser will support this tag. E.g. no

Confusion with meters in AVAudioRecorder

由 浪子不回头ぞ 提交于 2019-12-10 16:53:46
问题 Simply put, I'm trying to lip-sync something based on the decibel reading from the mic input stream of an iPhone, and the values I'm getting aren't quite what I'm after. I'm using AVAudioRecorder's peakPowerForChannel and averagePowerForChannel. (I'm aware that this is a rather simplistic lip-sync technique, but quality isn't a major concern). When the number of decibels increases, the meters react as I'd like them to (higher value when louder, so I can map this to the open-ness of the mouth)

How to measure noise or sound and displays in dB(A) in iphone?

由 强颜欢笑 提交于 2019-11-28 05:34:44
I want to measure sound in dB(A) in iPhone. How can I do it? Is there any example or tutorial? If you use AVAudioPlayer, you can use this method AVAudioPlayer *avPlayer = ... [avPlayer play...]; [avPlayer averagePowerForChannel:0]; [avPlayer averagePowerForChannel:1]; From Apple's doc - (float)averagePowerForChannel:(NSUInteger)channelNumber Description Returns the average power for a given channel, in decibels, for the sound being played. 来源： https://stackoverflow.com/questions/6183599/how-to-measure-noise-or-sound-and-displays-in-dba-in-iphone

How to style HTML5 <meter> tag

I am wondering how I could style the new <meter> tag. <meter value=80 min=0 max=100> 80/100 </meter> I just want to change the background color and the value color, but I can't find the right CSS properties.
