 |
| Instead of working on an image itself, this technique is often applied on its gradient image.
In this case, each object is distinguished from the background by its up-lifted edges |

| Image Segmentation |
|
| The goal of image segmentation is to cluster pixels into salient image regions, i.e., regions corresponding to individual surfaces,
objects, or natural parts of objects. A segmentation could be used for object recognition, occlusion boundary
estimation within motion or stereo systems, image compression, image editing, or image database look-up. |

| Multi-Resolution Method for Improving Image Search |
|
| Many applications of computer vision involve locating examples of known objects or structures in new images. Often the structures to be located can vary in shape, either because they are flexible or articulated, or because natural variation is present. Flexible
models have proved extremely useful in tackling such problems. |

|
| "Emeralds are usually concave so that they may concentrate the visual rays. The Emperor Nero used to watch in an Emerald the gladiatorial combats." The modern reinvention of spectacles occurred around 1280-1285 in Florence, Italy. It's uncertain who the inventor was. Some give credit to a nobleman named Amati (Salvino degli Armati, 1299 ). It has been said that he made the invention, but told
only a few of his closest friends |

| Wavelet and Multiresolution Processing |
|
| Unlike Fourier transform, whose basis functions are sinusoids, wavelet transforms are based on small waves,
called wavelets, of limited duration. Fourier transform provides only frequency information, but wavelet transform provides time-frequency
information. |

| Pyramid Methods In Image Processing |
|
| Digital image processing is being used in many domains today. In image enhancement, or example, a variety of methods
now exist for removing image degradations and emphasizing important image information, and in computer graphics, digital
images can be generated, modified, and combined for a wide variety of visual effects. |

| Homorphic Processing |
|
| The objective of the project is to study and implement the techniques of multiplicative homomorphic systems designed for enhancing the images in spatial domain. The image can be characterized by two components, (1) the amount of source illumination incident and (2) amount of illumination reflected by the object. |
