Today I tried the function getShape on the binary images extracted using getColor in yesterday’s post. I tried same function on different binary images and it worked fine but today it didn’t worked as expected. The circularities of shapes (square, circle, triangle) are intermixed. I mean these should be in a specified range for a certain shape. But results were not favorable. Hoping to get it finished soon.

Today got to listen about the introduction to Mobile Sensors like Accelerometer, Gyroscope, Proximity etc. A gyroscope is a device that uses Earth’s gravity to help determine orientation. An accelerometer is a compact device designed to measure non-gravitational acceleration. When the object it’s integrated into goes from a standstill to any velocity, the accelerometer is designed to respond to the vibrations associated with such movement.



Also came to know about LVM. LVM stands for Logical Volume Management. It is a system of managing logical volumes, or filesystems, that is much more advanced and flexible than the traditional method of partitioning a disk into one or more segments and formatting that partition with a filesystem.

One of my friend had Ubuntu installed as LVM system. He got some problem and could not boot from it. So I tried to mount it as I usually do using mount –bind /dev/sdxx/ /mnt/ from the live USB, but it didn’t work and gave some error saying it can’t mount lvm. Internet wasn’t working that time so I searched now and found something: http://www.tuxradar.com/answers/212 I can’t test it right now because I don’t have the LVM and I’m having manual partitioning.
