License-Plate-Detection
step 1 Convert the image into gray color and take DWT transform of gray colored image
step 2 Use sobel edge detcetion of vertical component of DWT transformed image
step 3 apply imclose, imopen morphological operations with strcutural co-efficient like
se=strel('rectangle',[20,30]); eroded=imdilate(edgy,se); eroded=imclose(edgy,se); se=strel('disk',10); eroded=imopen(eroded,se);
step 4 Use bounding box method to extract all possible bounding boxes and below condition to select the bounding box of license plate only
dim(jj)=BB(jj).BoundingBox(3)/BB(jj).BoundingBox(4); if dim(jj)>4 -- end
BoundingBox(3)= height BoundingBox(4)= width

step5Â crop the detected license plate and apply morphological operations again to extract the characters in license plate.
Step 5.1 Enhance the image edges by gradient enhancement operation
g=rgb2gray(cropedimg); % Converting the RGB (color) image to gray (intensity). g=medfilt2(g,[3 3]); % Median filtering to remove noise. se=strel('disk',1); % Structural element (disk of radius 1) for morphological processing. gi=imdilate(g,se); % Dilating the gray image with the structural element. ge=imerode(g,se); % Eroding the gray image with structural element. gdiff=imsubtract(gi,ge); % Morphological Gradient for edges enhancement.
Step 5.2 Eliminate the license plate edges and removing pixels area with more than 100 pixels results in segmented characters.
