A Tool for Determining Image Discriminability
نویسنده
چکیده
We describe discrim, a Matlab-based program for investigating image discriminability in various display systems. Discrim allows the user to manipulate images representing scene content. These images can be built up out of image primitives (sine wave gratings, Gabor patches) and image files from other sources. The user may then manipulate a model of the sensor and display characteristics. The sensor and display model consists of four stages: an initial spatial filter preceding the sensor, Poisson noise, a point nonlinearity (“Gamma”) and output noise. The user may view the effects each of these stages has on the image. Finally, the user may specify a pair of images as input to an image discriminability model.

Background: Most studies have investigated the effect of brain pathological aging on information recall and recognition memory performance of patients (by using a yes/no procedure), and for this reason, provide a partial picture of memory deficits and other factors involved in recognition memory such as discriminability and response bias are not considered. In this regard, the aim of present st...
متن کاملThe role of integral features for perceiving image discriminability
The computational model we propose deals with the measurement of image discriminability in such a way that the comparison of a pair of images is performed by matching the corresponding integral features registered within the same fixation point which a spatial sensitivity function directs about the images. © 1997 Elsevier Science B.V.

In land use planning, mapping the present land use / land cover situation is a necessary tool for determining the current condition and for identifying land use trends. In this study, in order to provide a land use/ land cover map for Ilam watershed, the IRS-1C image data from 25th April 2006 were used. Initial qualitative evaluation on data showed no significant radiometric error. Ortho-rectif...
متن کاملDiscriminability and reliability indexes: Two new measures to enhance multi-image face recognition
In order to handle complex face image variations in face recognition, multi-image face recognition has been proposed, instead of using a single still-imagebased approach. In many practical scenarios, multiple images can be easily obtained in enrollment and query stages, for example, using video. By accessing these images, a good ”quality” image(s) will be used for recognition using conventional...
متن کاملCluster-Based Image Segmentation Using Fuzzy Markov Random Field
Image segmentation is an important task in image processing and computer vision which attract many researchers attention. There are a couple of information sets pixels in an image: statistical and structural information which refer to the feature value of pixel data and local correlation of pixel data, respectively. Markov random field (MRF) is a tool for modeling statistical and structural inf...
