What are the problems in digital images?
Among the most common problems in digital photography are pictures that are incorrectly exposed and are too light or too dark . This problem is usually caused by the camera exposure system reading the background and compensating for it.

How difficult is image processing?
Not an easy task. Of course, you can attempt to simulate the way we see with two eyes by taking two pictures simultaneously and extracting 3D information from these. This is called stereoscopic vision. However, stitching images together is also not a trivial task and is, hence, likewise an open area of research.
What are the disadvantages of digital image processing?
By changing the image format and resolution, the image can be used in a number of media. Disadvantages of digital image: Misuse of copyright is now easier than it earlier was . For instance, images can be copied from the Internet just by clicking the mouse a couple of times.
How does image processing work?
Image processing basically includes the following three steps: Importing the image via image acquisition tools ; Analysing and manipulating the image; Output in which result can be altered image or report that is based on image analysis.
Is image classification difficult?
But in some cases there is certain object in image but the appearance of that object is very similar to the background, So in those case it is very difficult for image classification system to classify the object. ... That is all about challenges of image classification system.
What are the common flaws found in images?
- Camera shake is evident in the first photo.
- Focused on back, not eye or head.
- Watch the horizon when composing!
- Harsh shadows, washed out look and red-eye cause by direct flash.
- Original, sharpened, over-sharpened.

How long will it take to learn image processing?
I don't think you can learn much in 2 months. Image processing is really broad field, and to get better in it you'll need at least several years . Some of the very basics stuff you can do : take a look into 2d filters (or better yet find a book describing 2d image filtering).
Why image processing is important?
Image processing is often viewed as arbitrarily manipulating an image to achieve an aesthetic standard or to support a preferred reality. However, image processing is more accurately defined as a means of translation between the human visual system and digital imaging devices.
What is the scope of image processing?
Image Processing extracts information from images and integrates it for several applications . There are several fields in which image processing applications are relevant. Medical imaging, industrial applications, remote sensing, space applications, and military applications are a few examples.
What are the advantages and disadvantages of digital image processing?
The processing of images is faster and more cost-effective . One needs less time for processing, as well as less film and other photographing equipment. It is more ecological to process images. No processing or fixing chemicals are needed to take and process digital images.
What are the applications of image processing?
Some of the important applications of image processing in the field of science and technology include computer vision, remote sensing, feature extraction, face detection, forecasting, optical character recognition, finger-print detection, optical sorting, argument reality, microscope imaging, lane departure caution ...
What is the most common level of image processing?
In image processing, the input is a low-quality image, and the output is an image with improved quality. Common image processing include image enhancement, restoration, encoding, and compression .
