Privacy preserving camera

A method for privacy preserving comprising:

• obtaining a video stream captured by a camera and storing frames of the video stream in a frame buffer;
• detecting a moving object in the video stream;
• determining whether the moving object is a privacy protecting object;
• when the moving object is determined not to be the privacy protecting object, outputting the video stream;
• when the moving object is determined as the privacy protecting object:
• parsing the moving object in the video stream;
• removing at least a portion of the moving object from the video stream;
• filling an area of the removed moving object in the video stream with a compensated patch from a neighbor frame or a background of a current frame of the video stream;
• outputting a modified video stream having at least a portion of the moving object replaced with the compensated patch;
• performing a skin area detection to the moving object to determine a nakedness level of the moving object;
• determining an identity of the moving object;
• and
• determining whether to allow a first frame at a first time instance of the moving object to appear according to the object identity of the moving object in a second frame at a second time instance and the nakedness level of the moving object in the second frame at the second time instance, the second time instance being a later time instance of the first time instance.

A non-transitory computer readable medium storing executable computer program instructions for privacy preserving, the computer program instructions comprising instructions for:

• obtaining a video stream captured by a camera and storing frames of the video stream in a frame buffer;
• detecting a moving object in the video stream;
• determining whether the moving object is a privacy protecting object;
• when the moving object is determined not to be the privacy protecting object, outputting the video stream;
• when the moving object is determined as the privacy protecting object:
• parsing the moving object in the video stream;
• removing at least a portion of the moving object from the video stream;
• filling an area of the removed moving object in the video stream with a compensated patch from a neighbor frame or a background of a current frame of the video stream;
• outputting a modified video stream having at least a portion of the moving object replaced with the compensated patch;
• performing a skin area detection to the moving object to determine a nakedness level of the moving object;
• determining an identity of the moving object;
