Informative Research Topics in Image Processing

Image processing is a process in which the low quality of an image is inserted into the digital computer and as an output, a high quality image comes. It is also known as ‘Digital Image Processing. Image processing and computer vision are of significant importance to any field where images are supposed to be enhanced and analyzed. Areas, where they play an important role, are remote sensing, surveillance, inspection, and more.

Image processing is a unit of digital computation that has emerged as an academic discipline and is in demand today. Students of this field will benefit from the visual realization of various fundamental concepts and learn how to implement algorithms efficiently.

 

Following are some very creative and informative research topics in image processing:

 

Image Formation

 

It is a process in which radiometric and geometric processes are encompassed by which 2D images are formed from 3D objects. An illuminated object disperses light towards a lens that further focuses on the light to create an image.

 

Image Filtering

 

It is a theory that involves the use of window operations to perform important functions such as noise removal, image enhancement, and more. Image filtering is, therefore, a technique by which size, color, shape, and other characteristics of an image are filtered and enhanced. Various graphical editing techniques that are available on editing software are used to transform an image. Hence, it enhances and modifies an image.

 

Image Enhancement 

 

It is a process that highlights or eliminates specific information of an image such as noise removal, refining blurred details, and more. Image enhancement provides a better picture for the viewer to see.

 

Image Mosiacing

 

It is a process in which multiple images are constructed of the same scene into a larger image. The output of the image is the combination of the two images of the same scene. This technique is generally used on several images like digital images and more.

 

Image Histogram

 

It is a technique that acts as a graphical representation of tones of an image. It provides with different pixels for each tonal value. Nowadays, all digital cameras have an image histogram that helps in showing the distribution of tones. In the field of computer vision or image processing, an image histogram can be very useful in segmenting the images.

 

Image Deblurring 

 

It is the process of removing blurred features from an image, for example- an image taken from a digital camera turns out to be blurred due to shaken hands or the object. This image can be deblurred by using the image deblurring technique.

 

Underwater Imaging Techniques

 

It is one of the emerging research topics in image processing. An underwater image is a low-quality image due to absorption or dispersion underwater. Such images are corrected by using color balance and then white balance.

 

Remote Sensing

 

It is the process in which information about an object is gained without involving any physical contact with that object. It is opposite to on-site observation. Remote sensing is generally sued to know things about the earth. It helps in detecting and monitoring physical information about the earth. Researchers can ‘sense’ different things and activities of the earth with the help of remote sensing.

 

Edge Detection

 

It is another technique of image processing that finds the boundaries of the objects that are present within the images. It works by finding discontinuities in the brightness of the image. Edge detection is generally used in data extraction in areas such as image procession, machine vision, and computer vision. 

 

Image Morphing

 

It is a special effect that changes one image to another image and makes it look like a seamless transition. It can also be used in audio recordings, for example- change in voices or vocal lines. Different software is used for image morphing such as after effects, elastic reality, FantaMorph, Morpheus, morph thing, nuke, and more. 

 

Object Detection 

 

It is a computer technology of image processing that helps in detecting the examples of semantic objects in a specific image. With object detection, it becomes easy to find or locate or count the objects in an image and label them. 

 

We have listed above some important research topics in image processing for research students that will create a good base for their thesis by all means.
