Bit-plane slicing is a method which divides the image into many binary image planes and categorizes the image data into most significant and least significant information. In this paper a new edge detector using the most significant image data to detect the edges in the bacterial images is developed. This proposed method finds the edges in the higher order bit-planes using contouring technique ...

Abs-Laplacian is a newer technique for detecting edges. While the Sobel and Prewitt seems to be used predominantly in image processing due to better edge detection. However they need higher amount of complexity twice than that of abs-Laplacin. Moreover, qualities of images are no better than the newer kernel. While the new technique seems to perform better in speed and quality, there seems a bi...

HIS color space is based on the visual features of our eyes, and uses tone, brightness, saturation to manifest the color. While conducting edge detection on color images, in order to get better effects and consistent with human visual perception, a novel HIS-like color space is defined and it is obtained in the process of the improving HIS color model. Edge detection has been made on image whic...

Edge is a basic feature of an image. Edges can be defined as boundary between two different regions in an image. Edge detection refers to the process of identifying and locating sharp discontinuities in an image. Edge detection process significantly reduces the amount of data and filters out useless information, while preserving the essential structural properties in an image. .In this paper we...

We expand Crawford and Sobel’s (1982) model of information transmission to allow for the costly provision of ‘hard evidence’ in addition to conventional cheap talk. Under mild assumptions we prove that equilibria have an interval-partition structure, where types of the Sender belonging to the same interval either all induce the same action through cheap talk or reveal their types through hard e...

terms of an underlying causal or dispositional trait. Some infants are said to be strongly attached to an adult; others to be less strongly or not at all attached (e.g., Feldman & Ingham 1975) . Attachment is often operationalized in terms of a small number of "attachment behaviors." These include behaviors which promote proximity to presumed attachment figures and behaviors which are perhaps d...

Article history: Received 23 October 2007 Received in revised form 3 May 2010 Accepted 8 July 2010 Available online 3 August 2010 This paper compares different theoretical models of the structure of intelligence, based on the analysis of data obtained in a series of measured abilities corresponding to the Spectrum assessment activities (Gardner, Feldman & Krechevsky, 1998) in a sample of 393 ch...

We analyze relative performance of stochastic and deterministic mechanisms in an environment that has been extensively studied in the literature on communication (e.g., Crawford and Sobel, 1982) and optimal delegation (e.g., Holmström, 1984): a principal-agent model with hidden information, no monetary transfers, and single-peaked preferences. We demonstrate that under the common assumption of ...

Howmuch information should a policy maker pass on to a currently ill-informed citizen? In this paper, we address this classic question of Crawford and Sobel [1983] in a setting in which beliefs impact utility, as in Kreps and Porteus [1978]. We show that this simple amendment has far-reaching implications. In particular, our question cannot be answered using a utility function with standard rev...
