Lung diseases are the leading cause of death. Main factors that cause lung diseases are inhaling dusts, chemicals, or bacteria and molds at work. 70275 indian people were affected by lung disease among them 63759 people died. CAD system assists the doctors for the diagnosis of diseases in higher degree of perfection within a short period of time. High-resolution Computed Tomography (HRCT) is the preferred method for diagnosing a number of lung diseases. Ground glass structures are characterized by a slight increase in lung density, with persistent visibility of vascular structures and bronchial walls are imaged as abnormal lungs. Ground glass structure is a marker for pulmonary edema, desquamative pneumonitis, hypersensitive pneumonitis, pneumocystis carinii pneumonia. imageprocessing techniques play a significant role in the diagnosis of lung disease. This paper presents a novel imageprocessing method to identify the ground glass structure in lung CT images using mean intensity pattern identification. The results obtained show the feasibility of the proposed method to diagnose the ground glass structure of lung CT image.
Speckle reduction is desired to improve the quality of ultrasound images. However, a uniform speckle reduction from the entire image results in loss of important information, especially in cardiac ultrasound images. I...

Skin color segmentation is important for several imageprocessing, and computervision applications. But, the accuracy of a color-based skin detection method is affected by the presence of some skin-like colors in the background regions. So, probabilistic approaches are more suitable for the skin detection as compared to hard decision-based approaches. A Skin Probability Map (SPM) of an image provides the probability of a pixel belonging to skin region. It is observed that the accuracy of a SPM-based skin detection method also depend on the chosen colorspace for the SPM. In this paper, a novel Weighted Skin Probability Map (WSPM) is proposed for the skin color segmentation. The WSPM is represented as a weighted sum of the SPMs obtained from different color spaces. Experimental results based on standard databases show that replacing the single colorspace-based SPMs with the proposed WSPM can reduce the overall detection errors significantly.
