In this paper, we proposed a specular reflection suppression method for endoscopic images. To reduce the impact of specular reflection on visual quality, the proposed method is composed of two parts: reflection detection and reflection suppression. To detect reflection regions, a thresholding algorithm is used. To suppress the effect of specular reflection, a modified image inpainting algorithm is...
Medical imaging methods are very useful to monitor different diseases. In general, there are different scanning equipments are available like PET, MRI, and FMRI, US etc. These are useful to visualize different abnormalities of patients. But, most of the people and radiologists are interested to go for ultrasound (US) scanning to monitor the ultrasonic baby and other abdominal conditions. Because US...
In this paper, we discuss some of the key contributions in the current decade related to image retrieval and automated image annotation. General content-based image retrieval (CBIR) also could be improved by the proposed approach in a similar manner as text-based retrieval is improved. In this case no text information is available, but only visual features are used. The CBIR identifies relevant articles...
Age Related Macular Degeneration (ARMD) is a retinal disorder usually found in old people, which affects the central vision, but not the peripheral vision. The objective of this work is to develop an automated system for the classification of ARMD using digital fundus images, so that an intelligent computer aided system can be developed for the diagnosis of ARMD. from ARMD. Diagnosis and treatment...
Falsification of medicines is a big problem in many developing countries, where technological infrastructure is inadequate to detect these harmful products. We have developed a set of inexpensive paper cards, called Paper Analytical Devices (PADs), which can efficiently classify drugs based on their chemical composition, as a potential solution to the problem. These cards have different reagents embedded...
Diabetic macular edema (DME) is an eye disease that belongs to diabetic retinopathy which directs to vision loss. DME, which is a contusion in the macular region of eye is a common vision problem seen in diabetic patients. Hard exudates (bright lesions)in the fundus image indicates the presence of DME. Early detection of Macular Edema in diabetic patients prevents blindness. DME occurs when fluid...
Biomedical in vivo imaging has been playing an essential role in diagnoses and treatment in modern medicine. However, compared with the fast development of medical imaging systems, the medical imaging informatics, especially automated prediction, has not been fully explored. In our paper, we compared different feature extraction and classification methods for prediction pipeline to analyze in vivo...
The gray level co-occurrence matrix (GLCM) is widely used for textural feature extraction. The features obtained from GLCM matrix are subjected to the classifiers for the purpose of identification and classification. In this paper the combinations between different features, obtained from GLCM matrix, are studied. For experiments, the leaves of medicinal plants are considered, as proper identification...
In this paper, the SIMPLIcity (Semantics-sensitive Integrate Matching for Picture Libraries), an image retrieval system is introduced. The feature extraction is based on Histogram, color layout and coefficients of wavelet transform. This retrieving system adopts feature database for matching so as to reduce the search space which is especially useful in a larger image database. Retrieval images are...
This paper is dedicated to the development of a computer vision-based system for medication (pills and capsules) identification and counting in order to increase the productivity of medication dispensing and maintain its high safety. The algorithmic basis of the system is the attentive vision approach to robust and fast object detection in images. It consists in time-efficient image analysis by a...
This paper proposes a method to detect optic disk (OD) automatically in fundus image of retina without using background mask and blood vessels. Based on the properties of OD, an idea of curve operator is presented here. This method has been implemented on three public databases and the promising results are obtained. The experimental results indicate that this proposed method of automatic OD detection...
Automated annotation and grading for histopathological image plays an important role in CAD systems. It provides valuable information and support for medical diagnosis. Currently, computer-aid analysis of histopathological images mainly relies on some well-designed digital features, which requires abundant human efforts and experiences in problem domain. Learning a good feature representation from...
Quantitative analysis of skin wound is critical in objective evaluation of a therapy. In this paper, a robust wound segmentation method is presented. The proposed method uses gradient vector flow (GVF), therefore, the segmentation is quite stable to variation of color characteristics of a camera used for image capture or illumination.
This paper reports temperature indicator for surgical simulator and temperature calculation method using image processing for visualization of temperature increase and distribution in the arterial biological model. The indicator consists of polydimethylsiloxane (PDMS) and thermochromic pigment presenting non-reversible color change according to temperature. The indicator has transparency to observe...
The three-dimensional visualization of medical images can provide the basis for the doctor's diagnosis, and has good application prospect in medical diagnosis. According to the characteristics of human skeletal image, first of all, Gaussian filter is used to remove noise from the image while preprocessing the image. Secondly, the fast ray casting algorithm is applied to realize the 3D visualization...
The shape and size of retinal vessels have been prospectively associated with cardiovascular outcomes in adult life, and with cardiovascular precursors in early life, suggesting life course patterning of vascular development. However, the shape and size of arterioles and venules may show similar or opposing associations with disease precursors / outcomes. Hence accurate detection of vessel type is...
In recent years, new optical microscopes have been developed, providing very high spatial resolution images called Whole Slide Images (WSI). The fast and accurate display of such images for visual analysis by pathologists and the conventional automated analysis remain challenging, mainly due to the image size (sometimes billions of pixels) and the need to analyze certain image features at high resolution...
Play for Health (P4H) is a telemedicine service consisting of a telerehabilitation platform to improve cognitive and physical deficits through the use of serious games and various videogames controllers. This paper states that there are issues that could benefit the rehabilitation process using serious games. We present the P4H platform as an example of success in telerehabilitation based on serious...
The paper presents a new technique for archiving and protecting content of visual medical information. A special format is developed based on a new Inverse Pyramid decomposition. The images are archived with the highest quality but their restoration is performed in accordance with the application. The image content is protected by inserting multiple fragile watermarks that can be extracted by authorized...
Comparative analysis of the biomedical image segmentation methods is presented in this paper. The segmentation methods are offered on the basis of previous labeling and spatial moments. Experimental results show that the developed methods have higher accuracy by signal-noise ratio (up to 40%) compared to the nowadays known.
