Plant diseases have turned into a dilemma as it can cause significant reduction in both quality and quantity of agricultural products. Automatic detection of plant diseases is an essential research topic as it may prove benefits in monitoring fields of crops, and thus automatically detect the ...
Histogram Stretching in Digital Image Processing - Learn about histogram stretching techniques in digital image processing to enhance image contrast and improve visual quality.
In a subsequent paper, Srinivas and Bhandari [128] observe that most low-light enhancement techniques affect the correctly exposed area while enhancing the under-enhanced area. By combining the adaptive sigmoid transfer function (ASTF) with the Laplacian operator, they are able to produce an ...

It involves setting the lowest and highest histogram bins before shifting the histogram, which can be done in one step. This method is often used in lossless or reversible cover image techniques and can also be applied in the transform domain based on error prediction. It has been combined ...
2. Image Enhancement Image enhancement refers to the process of transforming an image so as to make it more visually appealing or to facilitate further analysis.5It can involve simple operations (addition, multiplication, logarithms, etc.)6or advanced techniques such as contrast stretching...
So denoising of an image is a basic step in medical image processing. The normally used filtering techniques are, median and mean filters=-=[2]-=- .But, a single smoothening or median filter is not enough to remove the noise completely. 2. TYPES OF NOISES IN MEDICAL IMAGES 2.1. ...
