# operations called Morphological operations such as Dilation, Erosion etc. and a working MATLAB ( MATLAB by Mathworks ) Program has been created that

SE can also be an array of strel object or offsetstrel objects, in which case imerode performs multiple erosions of the input image, using each structuring element in succession. imerode performs grayscale erosion for all images except images of data type logical.

se = strel ( 'line' ,11,90); Erode the image with the structuring element. erodedBW = imerode (originalBW,se); View the original image and the eroded image. DILATION AND EROSION • Dilation adds pixels to the boundaries of objects in an image • Erosion removes pixels on object boundaries Brainbitz 4. DILATION • It grows or thicken objects in a binary image • Thickening is controlled by a shape referred to as structuring element • Structuring element is a matrix of 1’s and 0’s Brainbitz 5.

For erosion that means you will take the minimum value between the intensity at current position under inspection and only itself, so there is nothing else to output than the intensity at the current position. This is the same for dilation. To check that, verify any correct text that describes the formulas for erosion and dilation. And, in Matlab: Image Erosion without using MATLAB function 'imerode'. In MATLAB, 'imerode' is a function used to make the objects thin.

It can be installed easily: $ sudo apt-get install octave-image The most basic morphological operations are dilation and erosion. Dilation adds pixels to the boundaries of objects in an image, while erosion removes pixels on object boundaries. The number of pixels added or removed from the objects in an image depends on the size and shape of the structuring element used to process the image.

## Code for Erosion:clcclear allclose allwarning offa=im2bw(imread('Capture.JPG'));imshow(a);title('Origina Image');[r c]=size(a);w=ones(3,3);output=[];for x=2:

Dilation makes objects more visible and fills in small holes in the object. Remove Thin Lines Using Erosion.

Erosion is the local min and dilation is the local max.

Dilation using bit packing is described in [3] . For erosion that means you will take the minimum value between the intensity at current position under inspection and only itself, so there is nothing else to output than the intensity at the current position.
