Detecting and Disabling Digital Cameras using Image Processing Techniques

ECE533 Digital Image Processing Image Denoising Using Wavelet Thresholding Techniques

Wavelet transforms enable us to represent signals with a high degree of scarcity. Wavelet thresholding is a signal estimation technique that exploits the capabilities of wavelet transform for signal denoising. The aim of this project was to study various thresholding techniques such as SureShrink, VisuShrink and BayeShrink and determine the best one for image denoising.

Feasibility of detecting and localizing radioactive source using image processing and computational geometry algorithms

We consider the problem of finding the localization of radioactive source by using data from a digital camera. In other words, the camera could help us to detect the direction of radioactive rays radiation. Therefore, the outcome could be used to command a robot to move toward the true direction to achieve the source. The process of camera data is performed by using image processing and computa...

Detecting Imperfections in Steel Blades Using Digital Image Processing

Blade imperfections are a significant explanation behind low quality and of shame for makers. Review forms done on these commercial ventures are for the most part manual and tedious. To diminish mistake on recognizing sharpened steel deformities requires more auto and precise review process. Considering this failing to offer, this examination actualizes a Blade Defect Recognizer which utilizes ...

Assessing of Fabric Appearance Changes Using Image Processing Techniques

 This paper describes the use of image processing to measure lightness changes of fabric appearance. The lightness changes due to dyeing, washing and exposure to light treatments are studied. These properties are measured by using the changes in the intensity levels of the fabrics image and the L* obtained by a spectrophotometer. For each case, analysis of variance (ANOVA) is carded out and the...
