Soil is one of the natural material, which has the different features for the particular characteristics. In digital imageprocessing is the principle to simplify the identification of soil features. Soil consists of both physical and chemical characteristics. These characteristics are used to find the field of soil usage. Thresholding is the conversion of colour image into binary image and that is used for shape based identification. It applicable for feature extract from curvature, valleys, and non-smoothening surfaces and it enhances the feature and get more information. Fractal dimension is one of the soil feature. A new model is proposed to assign various threshold values apply to the same sample and to determine the range and also the best image model (Red-Green-Blue, Hue-Saturation-Value, Hue-Saturation-Luminance and Hue-Saturation-Intensity) of soil samples. The device can also be modelled as most powerful tool for prediction of land usage for various fields such as agriculture and construction.
Contourlet transform lacks shift invariance, and threshold processing on the coefficients may produce pseudo Gibbs phenomena. For recursive cycle spinning algorithm can reduce the pseudo Gibbs phenomena. This paper st...

Medical image three-dimensional model reconstruction technology, which uses two-dimensional medical image sequence to reconstruct three-dimensional model, provides doctors with intuitive, comprehensive and accurate information of lesions and normal tissues, is one of the hotspots in the field of medical imaging. According to different reconstruction models, virtual arbitrary cutting is realized, and surface cutting and volume cutting, and the interactive method of virtual cutting is discussed. The minimum error in merging is calculated to determine the location of the new vertex. Using the toolkit and library to develop a medical image 3D model reconstruction and visualization system, can read medical image data in a specific format, perform 3D model reconstruction, and finally real-time interaction. The experimental results show that the proposed method can effectively preserve the graphical features of the original model and provide convenient use for real-time rendering. The VTK toolkit and library developed a medical image 3D model reconstruction and visualization system that can read medical image data in a specific format, perform 3D model reconstruction, and ultimately real-time interaction.

image segmentation is a process of dividing image into smaller parts to identify the individual objects. Often, this process helps in the quantification of digital images related to disease complications for metabolic process. This work reports on the use of computer-aided modelling tools and rapid prototyping technology to document, preserve and reproduce in three dimensions, and historic machines and mechanisms are used for accurate medical diagnosis. Epidemiological and clinical trials have confirmed the greater incidence and prevalence of deaths due to the inability to acquire qualitative information from the acquisition of images in primary stage itself. Rapid prototyping gives a better understanding of clinical and physiologic mechanisms of various disorders and pain, lesion detection. In image segmentation process, thresholding method is suitable for defining optimal value for identification and detection of region of interest. The standard uptake value (SUV) is based on selecting threshold value to utilize a similarity metric between the grey level of image and data points obtained from the threshold values. This is based on the intensities or inhomogeneity of clustering framework. Affinity propagation is used for images as a matrix by measuring the square patches from similarity texture. A major challenge in computervision is to extract this information directly from the images available to us, help users, and to see and feel as an actual part in order to bring a computerimage to life. Actually, the framework is given by PET-CT images which is used to identify and detect malignant tissues in a human body with accurate measurements of SUVs. This process involves ROI identification, segmentation, rendering and SUV functional quantification for promising results. The results obtained from computer modelling are transformed into real substance by rapid prototyping technology to feel and provide accurate diagnosis to patient.
