Model Based Adaptive Enhancement of the Infrared Image Sequence

چکیده
In literatures two enhancement algorithms spatial and spatiotemporal homomorphic ltering SHF and STHF have been proposed for enhancement of the far infrared image based upon a far infrared imaging model Although spatiotemporal homomorphic lter ing may reduce the number of iterations greatly in comparison to spatial one for a similar degree of con vergence by making explicit use of the additional in formation provided temporally the enhanced results from SHF are in general better than those from STHF In this paper we design an adaptive spatiotemporal homomorphic ltering ASTHF which can not only produce enhanced images as good as those from SHF but keep the number of iterations as low as that of STHF even lower for a similar degree of convergence as well

Image Enhancement Using an Adaptive Un-sharp Masking Method Considering the Gradient Variation
Technical limitations in image capturing usually impose defective, such as contrast degradation. There are different approaches to improve the contrast of an image. Among the exiting approaches, un-sharp masking is a popular method due to its simplicity in implementation and computation. There is an important parameter in un-sharp masking, named gain factor, which affects the quality of the enh...
متن کاملAdaptive Image Dehazing via Improving Dark Channel Prior
The dark channel prior (DCP) technique is an effective method to enhance hazy images. Dark channel is an image with the same size as the hazy image which represents the haze severity in different places of the image. The DCP method suffers from two problems: it is incapable for removing haze from smooth regions, causing blocking effects on these areas; it cannot properly reduce a haze with a no...
متن کاملStatistical Wavelet-based Image Denoising using Scale Mixture of Normal Distributions with Adaptive Parameter Estimation
Removing noise from images is a challenging problem in digital image processing. This paper presents an image denoising method based on a maximum a posteriori (MAP) density function estimator, which is implemented in the wavelet domain because of its energy compaction property. The performance of the MAP estimator depends on the proposed model for noise-free wavelet coefficients. Thus in the wa...
متن کاملRobust Potato Color Image Segmentation using Adaptive Fuzzy Inference System
Potato image segmentation is an important part of image-based potato defect detection. This paper presents a robust potato color image segmentation through a combination of a fuzzy rule based system, an image thresholding based on Genetic Algorithm (GA) optimization and morphological operators. The proposed potato color image segmentation is robust against variation of background, distance and ...
