Project Wild Penguin 22.4.2017: To delete directories inside current directory whose contents are less than a given size

By -

With GNU find and GNU coreutils, and assuming your directories don't have newlines in their names:

find . -mindepth 1 -maxdepth 1 -type d -exec du -ks {} + | awk '$1 <= 50' | cut -f 2-

This will list directories with total contents smaller than 50K. If you're happy with the results and you want to delete them, add | xargs -d \\n rm -rf to the end of the command line.

Command:

find . -mindepth 1 -maxdepth 1 -type d -exec du -ks {} + | awk '$1 <= 50' | cut -f 2- | xargs -d \\n rm -rf

ANPR Project Day 1: Standard Format of Indian Number Plate

By -
Image
The main purpose of ANPR project is to recognize the characters present in the number plate. To do this first, understanding the standard format of Indian Number Plate is required.  Since June 1, 2005, the Government of India has introduced High Security  Registration (HSR) number plates which are tamper proof. All new motorized  road vehicles that come into the market have to adhere to the new plates, while  existing vehicles have been given two years to comply with. Features  incorporated include the number plate having a patented chromium hologram; a  laser numbering containing the alpha-numeric identification of both the testing  agency and manufacturers and a retro-reflective film bearing a verification  inscription "India" at a 45-degree inclination. The numbers would be embossed  on the plate, rather than being painted for better visibility. The term "India" is to  be in a light shade of blue.  But still most of the vehicles don't follow this format.

ANPR Day 5: User requirement Analysis

By -
Today, analysis of user requirements was done taking under consideration the constraints and research work done. The User Requirement Analysis suggest that the main priority is to develop a simple and cost-effective system that is able to recognise characters from a given number plate image. Taking this into consideration following specifications are made: Instead of IR cameras, normal 5MP cameras will be used. Number Plates of Private Vehicles like cars that are medium-sized and follow standard number plate format will be considered. No special cases like VIP number plates and temporary number plates will be considered.  To train the system, non-indian number plate images can be used to meet the desired data set requirements.
