i.Boosting for Image Classification
Multimedia and Expo, 2007 IEEE International Conference on, 2007Traditional boosting method like adaboost, boosts a weak learning algorithm by updating the sample weights (the relative importance of the training samples) iteratively. In this paper, we propose to integrate feature re-weighting into boosting scheme, which not only weights the samples but also weights the feature elements iteratively.

Image classification and interpolation
SPIE Proceedings, 2012We have developed a novel interpolation method for images containing text, graphics and natural scenes. The method allows us to select the best interpolation algorithm for different regions of an image. In particular, we segment the image into graphical and natural regions and use the appropriate algorithm for each region.

Signal Processing, 2006
The automatic classification of images is now widely used in a range of applications. These include the diagnosis of arthritis from joint images, the classification of environmental noise from spectrograms and automatic text analysis. However, satisfactory performance is difficult to achieve in uncontrolled environments, as images are often ...

Image redundancy and classification
1995C.E. Shannon in his Information Theory defined the rate of information transmission of a transmitter-receiver couple, also called system mutual information. This concept can be applied to a simple model considering an image as a set of isolated pixels in order to define an image redundancy measure.

Image Classification Techniques
2021The image processing task, aimed at interpreting and classifying the contents of the images, has attracted the attention of researchers since the early days of computers. With the advancement of computing system technology, image categorization has found increasingly broader applications, covering new generation disciplines such as image analysis ...

On the classification of image features
Pattern Recognition Letters, 1990While the primary purpose of edge detection schemes is to be able to produce an edge map of a given image, the ability to distinguish between different feature types is also of importance. In this paper we examine feature classification based on local energy detection and show that local energy measures are intrinsically capable of making this ...

AbstractThere are tremendous content‐based retrieval systems. Most of them are applied to general image databases. Some were proposed for specified databases such as texture databases, ancient paintings, document image databases, digital mammography, face image databases, etc. However, there are fewer for plant databases.

Digital Investigation, 2006
Investigations involving massive quantities of graphics files that must be reviewed and classified require more robust tools to facilitate review and categorisation of massive numbers of graphic files. Traditional forensic tools are not equipped for such large-scale categorisation tasks this paper introduces some techniques that can streamline the ...

Image Classification by Web Images
2002While main targets of conventional Web mining are numerical and textual data, we propose Web mining for image data. Thanks to the recent rapid spread of digital imaging devices, demand for generic image classification of various kinds of real world images becomes greater.

Abstract Process monitoring using imaging can provide valuable information. However, the large number of images obtained necessitate automated classification into those showing “good” and “bad” product. This paper shows how a database of reference images can be used to modify image quality so as to obtain extremely high classification accuracies. The
