Am trying to detect number plate from an image.I have converted an image to grayscale and segment image. Now i have to find and filter blobs from an image and to detect number plate from an image. I will explain what i did..
I jus read segment image
license_plate = cv2.imread('license1_segmented.png',cv2.CV_LOAD_IMAGE_COLOR)
license_plate_size = (license_plate.shape[1], license_plate.shape[0])
mask = cv2.cv.CreateImage (license_plate_size, 8, 1)
cv2.cv.Set(mask, 1)
thresh_image_ipl = cv2.cv.CreateImage(license_plate_size, cv2.cv.IPL_DEPTH_8U, 1)
cv2.cv.SetData(thresh_image_ipl,thresh_image.tostring(),thresh_image.dtype.itemsize * 1 * thresh_image.shape[1])
min_blob_size = 100 # Blob must be 30 px by 30 px
max_blob_size = 10000
threshold = 100
**myblobs = CBlobResult(thresh_image_ipl,mask, threshold, True)**
myblobs.filter_blobs(min_blob_size, max_blob_size)
blob_count = myblobs.GetNumBlobs()
trying to find and filter blobs from an image.But am getting error while passing the parameters to CBlobResult which i highlighted above code.I mentioned the error below what i get while passing.
Traceback (most recent call last):
File "rectdetect1.py", line 110, in <module>
myblobs = CBlobResult(thresh_image_ipl,image_area, threshold, True)
File "/home/oomsys/pyblobs-read-only/blobs/BlobResult.py", line 92, in __init__
this = _BlobResult.new_CBlobResult(*args)
NotImplementedError: Wrong number or type of arguments for overloaded function 'new_CBlobResult'.
Possible C/C++ prototypes are:
CBlobResult::CBlobResult()
CBlobResult::CBlobResult(IplImage *,IplImage *,int,bool)
CBlobResult::CBlobResult(CBlobResult const &)
Anyone help me to find out the erros and to solve this and all... Thanks in advance...
