2013-05-31 09:13:48 -0600 | asked a question | findContours() error with cairo Hi, I'm using Kinect with OpenCV 2.4.5 using freenect. Below is my code: The error I'm getting is as follows: /build/buildd/cairo-1.10.2/src/cairo-surface.c:1287: cairo_surface_set_device_offset: Assertion `status == CAIRO_STATUS_SUCCESS' failed. Aborted (core dumped) I spent 5 hours on the internet searching for this, but still am clueless about this. Please help. |

2012-12-30 06:04:10 -0600 | asked a question | 16-bit conversion problem While printing values from a 16-bit Mat I'm getting only the lower 8-bit part of the number. For example if the number is 324, I'm getting the printed value as 68 which is 324-256. In the code below Ix_Ix is the element-wise multiplication of Ix, but it does not print values greater than 255. Instead it gives the lower 8 bits. Is there a problem with my code? How do I get the correct values? |
