• How to have the camera 'desynchronized' with Illumination changes ?

  30 juillet 2020, par vasudha

  For my current project, I have to record a video stream from a USB camera connected to Raspberry-Pi. While recording the videos if there are any illumination changes the camera should not synchronize it's preview/recording to the light change. Instead it should only record what it sees without any changes from camera input(for ex : exposure, contrast or brightness).

  


  


  1. I tried making changes in FFMPEG config and reinstalled it but it doesn't seem to work.

     


  


  2. I turned off auto_exposure with opencv but that wasn't useful either.

     


  


  


  I am using OpenCV for recording the videos later from which face recognition and skin-type classification will be done. So it is important that the Face color is not altered by the camera automatically with external illumination change. Can someone please help me with this ? Thanks.

• Community survey revealed – Discover the profile of a Piwik user

  7 novembre 2017, par Piwik Core Team — Community

  In January 2017 we launched a Piwik community survey which gathered more than a thousand responses. It is now time for us to release the results of this study. We release today the results of this survey painting a picture of the growing Piwik Analytics community !

  What types of businesses are using Piwik ?

  Just a reminder : Piwik is currently used on over 1 million websites and mobile apps.

  

  According to the community survey, 75% of businesses using Piwik are small companies and 25% are medium to large enterprises. Out of those 25%, more than 7% are large enterprises with more than a 1,000 of employees.

  Why choosing Piwik ?

  With a large majority, Open Source came first with almost 50% of the answers, then come the data security aspect (27%) in third comes the raw data access (10,5%) and for a minor part customizability with 1,9%.

  How often is Piwik used ?

  92% of respondents said that they are using Piwik regularly (at least once per month) :

  • on a daily basis 28%
  • on a weekly basis 41%
  • on a monthly basis 23%

  Is Piwik mostly installed on Intranet or External websites ?

  

  Piwik is mainly installed on external websites, 80% of the cases. However, 12% of respondents answer that they are using it on intranet too. The remaining 8% have chosen not to answer.

  Which CRM for Piwik users ?

  As CRM is a high valuable asset within the company, we wanted to check if there were any needs for Piwik to develop something specifically for CRM.
  The answers showed us that in almost 60% of the cases no CRM was used at all, for the rest there is no clear leading CRM which is used more than others.

  Do Piwik users wish more integrations to third party applications such as CRM, support systems ?

  60% of responders said no, which can clearly be understood from previous question. But the 40% remaining are clearly showing that they wish more integrations. We heard you, we are constantly updating our integration page. If there are any integrations you wish to have, do not hesitate to contact the solution provider and suggest them to integrate their product with Piwik.

  How do Piwik users get notified when a KPI reach a specific value ?

  Great question, great answers. Almost 50% of responders are not notified when something happens in Piwik and prefer to have a look at the UI instead. 15% did not know that it was possible using Custom Alerts but may have a look it. Some of you are also designing their own system. It made us realize here that we need to change our UI and integrate custom alerts to the main UI directly. Custom alerts is a great feature that you can access within the administration panel to get notified when something happened in your Piwik data.

  

  Which improvements could be made to Piwik ?

  Only 20% of you answered to this question, which is a good thing for us
