Fast Cartoon-Texture Decomposition Filtering Based License Plate Detection Method

Algorithm 1

Proposed LPD algorithm.

Input: Input car image

(1) Gray scale conversion: converse RGB color image into gray-scale image

(2) Improved edge detection: we first decompose image as , then detect the edge

(3) LPD approach: we detect LP by morphological filtering and LP screening,

(4) Tilt angle detection and correction:

Output: Output license plate:
