Dataset 1: 1048 categories,
1.	keep images containing at least one medium/large size logo (>=32*32 pixels)
2.	Remove images which aspect ratio >4 or <0.25
3.	remove categories with containing less than 20 logos after step 2.
4.  random rotate image from step 3 [-10,10] degree 3 times
5.  merge the data from step 3 & 4
