We have developed a tourist map system based on the way people create associations between colors and affective words related to tourist attractions. This study examines such associations. In the first experiment, a participant was required to choose one color from among the seven rainbow colors and one gray-scale level from among seven gray-scale levels to associate with an affective word rela...

It is well known that adult humans detect snakes as targets more quickly than flowers as the targets and that how rapidly they detect a snake picture does not differ whether the images are in color or gray-scale, whereas they find a flower picture more rapidly when the images are in color than when the images are gray-scale. In the present study, a total of 111 children were presented with 3-by...

Introduction O. J. Ginther stated: “gray-scale diagnostic ultrasonography is the most profound technological advance in the field of large animal research and clinical reproduction since the introduction of transrectal palpation and radioimmunoassay of circulating hormones.” (Ginther, 1986). It is hard to imagine that many discoveries and procedures related to ovarian, uterine and fetal functio...

BACKGROUND To date, there has been little agreement on the use of ultrasonographic parameters in predicting the long-term outcome after transplantation. This study evaluates whether ultrasonography of the graft performed in the early stage after transplantation is a valuable predictor for long-term-outcome. OBJECTIVES The aim of this study was to evaluate the association of ultrasonographic p...

A method for enhancing the contrast of gray scale images using multiscale mathematical morphology is presented in this paper. The conventional theoretical concept of enhancing image has been extended from mathematical morphology to multiscale mathematical morphological approach. Gray scale images sometimes suffer from lack of contrast. So to enhance image efficiently a multiscale top hat transf...

Recently inverse halftoning techniques are applied in many image processing applications, in which an efficient inverse halftoning method, that provides high quality gray-scale image from any binary halftone image, is required. In this paper we propose two neural networks based inverse halftoning methods, which are Multilayer Perceptron (MLP)-based and Radial Basis Function (RBF)-based inverse ...

PURPOSE Fatty liver infiltrations and fatty sparing impair diagnostic performance of grey-scale ultrasonography in differentiating malignant and benign focal liver lesions. In the study, we present our experience in diagnosing focal fatty liver infiltrations and focal fatty sparing with contrastenhanced ultrasonography (CEUS) in comparison to grey-scale ultrasonography and contrast-enhanced com...

The aim of this work was to show contribution of power Doppler imaging in the diagnosis of the carotid body tumors. Six patients with a nontender mass beneath the mandibular angle were evaluated with gray scale and power Doppler sonography. Well-defined, solid, weakly hyperechoic masses were noted on gray scale sonography in the carotid bifurcation. Power Doppler sonography showed abundant flow...

We present a Size-Intensity Diagram, based on a gray-scale granulometry. For this we use a cylindrical structuring function with two varying parameters: the radius r and the height (or intensity) k. The measurement associated with this gray-scale granulometry is based on the volume measurement commonly used in the classical gray-scale granulometry. The proposed diagram is therefore a bidimensio...
