To remove small size transitions and emphasize continuous transitions along the door column in Matlab, we can use morphological operators such as imerode, imdilate, imopen, and imclose. Morphological operators are image processing techniques that use the shape and size of a structuring element to modify and manipulate the shape, size, and orientation of objects in an image.
To remove small size transitions, such as noise, we can use imerode, which is a morphological operator that takes the minimum pixel value in the neighborhood of each pixel in the image. This operator shrinks the white regions and expands the black regions and can be used to remove small white noise from images.
To emphasize continuous transitions along the door column, we can use imdilate, which is a morphological operator that takes the maximum pixel value in the neighborhood of each pixel in the image. This operator expands the white regions and shrinks the black regions and can be used to emphasize continuous white regions in images.
We can also use imopen, which is a morphological operator that performs erosion followed by dilation. This operator is useful for removing small black regions and breaking thin white regions in images.
Finally, we can use imclose, which is a morphological operator that performs dilation followed by erosion. This operator is useful for closing small holes in white regions and joining short gaps in white regions.
Here is an example code that demonstrates the use of morphological operators to remove small size transitions and emphasize continuous transitions along the door column in Matlab:
