Hello,
My name is Ryuji Narita from LINX Corporation in Japan.
I want to get the Area of Blob with sub pixel in VisualApplets but I have no idea.
If you have any ideas, could you share it with me?

Hello,
It is not possible to get an object area in sub-pixel precision. Area is always returned in unit pixels, because a single pixel is part of an object or not, since the VA blob analysis is working on binary images.
Concerning sub-pixel precision and blob analysis it is normally about:
The object's center of gravity (COG) position is getting returned by not nomalized sub-pixel precision,
which means you have to divide the COG x & y components by the area to get sub-pixel precision.
Simply add fixed point precision bits to the required division.
Best regards,
