Loading an RGB image: The image whose number plate recognition is to be done is loaded. Fig.3. Loading an image. Grayscale. conversion: This RGB image is converted to grayscale image using cvCvtColor() function. Fig.4. Grayscale Image. Histogram equalization: Histogram equalisation is performed on this image using cvEqualizeHist() function. Fig.5

Finally, we can convert an intensity image into a binary image using the command im2bw(f, T), where T is a threshold in the range [0, 1]. Matlab converts f to class double, and then sets to 0 the values below T and to 1 the values above T. The result is of class logical. See the following example. We wish to convert the following double image

The spatial domain is the domain of the sampled image data, normally RGB values. Here is a definition of the frequency domain [3]: Here is a definition of the frequency domain [3]: The frequency domain is a space in which each image value at image position F represents the amount that the intensity values in and image vary over a specific distance related to F.

Next, implement in MATLAB a function that performs histogram equalization by (1) converting an input color image from RGB to HSV color space (using rgb2hsv which creates a double image), (2) computing the histogram and cumulative histogram of the . V (luminance) image only, …

Convert image to either grayscale or RGB. I find Colour conversion more effective when wanting to use a dynamic background subtraction. 4. Preproccessing. Either Colour, Grayscale or Binary depending on your input conversion. Background subtraction is for subtracting a static image in the form of a bmp file acquired from the main display of swistrack (right click image, ‘save displayed image ...

2010-11-05 · The thresholding options within the LEAF GUI allow the user to convert RGB or grayscale images into binary images (1’s and 0’s). This is a critical step as almost all subsequent cleaning and segmentation functions within the LEAF GUI act on binary images. There are three options within the thresholding button group: adaptive thresholding, global thresholding, or a combination of the two ...

As such, it would be more advantageous to convert YUV to RGB with the conversion mentioned above, and then convert the RGB data to gray-scale. This would yield more than 16 levels of gray. 2.1.5. White Balance . Balancing the colors and keeping the images looking realistic is the point of white balance. Depending on what type of camera is chosen, there may or may not be white balance ...
