Detects the car License plate and segment characters by morphological operations

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
