computer vision - What is the number of Hash functions needed in Bundle Min Hashing for Logo Recognition? -

लोगो के संदर्भ में लोगो मान्यता के लिए बंडल न्यूनतम हैशिंग:

मान लीजिए कि हमारे पास बंडल {2,5,18,444,678} और {2,5,79,368,841} हैं और शब्दावली का आकार 1M है यदि हमारे पास केवल 1 स्केच प्रति बंडल है तो हमें 1 हां फंक्शन की आवश्यकता है जो 1 एम पूर्णांक को [0,1] में समान वितरण से मूल्यों के निर्धारण के लिए निर्धारित करता है। प्रत्येक कॉल के लिए हैश फ़ंक्शन को निश्चित बीज होना चाहिए। 4-स्केच के लिए हमें 4 बीजों के साथ ही हैश फ़ंक्शन की आवश्यकता होती है। क्या विचार सही है?

या हम बेतरतीब ढंग से सेट (बंडल) से न्यूनतम हश शब्द के रूप में एक संख्या चुन सकते हैं, क्योंकि वे सेट के यादृच्छिक क्रमबद्धता का प्रतिनिधित्व करते हैं?

कागज में आवश्यक हैश फ़ंक्शंस?

क्या मुरमुरहेश 3 काम कर सकता है?

c++ - Qt-how to convert a QByteArray to struct -

I need to convert a QByteArray into a structure. I have such a structure: struct mavlink_attitude_t {/// & lt; Summary & gt; Timestamp (millisecond from system boot) & lt; / Summary & gt; Quint 32 Time_boot_ms; /// & lt; Summary & gt; Roll angle (rad, -pi .. + pi) & lt; / Summary & gt; Float roll; /// & lt; Summary & gt; Pitch angle (red, -p + + pi) & lt; / Summary & gt; Boat pitch; /// & lt; Summary & gt; Angle of O (Red, -P. + Pi) & lt; / Summary & gt; Float yao; /// & lt; Summary & gt; Angular Speed ​​Roll (Rod / S) & lt; / Summary & gt; Float rollspeed; /// & lt; Summary & gt; Pitch angular momentum (rad / s) & lt; / Summary & gt; Float pitchspid; /// & lt; Summary & gt; Yoga's angular momentum (RD / S) & lt; / Summary & gt; Float Yspeed; }; And I come from a Quetbeat Serial Port. I was already using the union but I think it can not be used for QByteArray, i...

c# - How to know the number of Threads created and limit the Tasks accordingly -

-
It is very clear that with task as async / await Instead of calling the asynchronous call threads , my question is: Is there a way to monitor threads while completing these tasks? This is because I can decide an optimal number of times for the thread that the thread does not eat too many CPU cycles at the same time (the CPU is intensive to handle the work). We take an example below (output is also mentioned) Although the program is completed in 5 seconds, but it has two threads (id = 1,4 ) if I increase the number of 6 instead of 2, then it creates 4 threads I know that this is the CLR thread OS thread (which is 4 in my machine Are), but I would like to know how they are mapped O (with actions) and use the same CPU. Is there any way to get it? Test code Fixed zero main (string [] args) {RunTasksWithDelays (). ); } Static async Task Run Task with Dislay () {Stopwatch S = Stopwatch. Startup (); Console.light line ("thread id =" + thread.content.trade.manag...
