An Integrated Content and Metadata based Retrieval System for Art
In this paper we describe aspects of the Artiste project to develop a distributed content and metadata based analysis, retrieval and navigation system for a number of major European Museums. In particular, after a brief overview of the complete system, we describe the design and evaluation of some of the image analysis algorithms developed to meet the specific requirements of the users from the museums. These include a method for retrievals based on sub images, retrievals based on very low quality images and retrieval using craquelure type
Cells Detection and Segmentation in ER-IHC Stained Breast Histopathology Images
In this paper, we present our recent work on cells
detection and segmentation in estrogen receptor immunohistochemistry (ER-IHC)-stained breast carcinoma images. The
proposed cell detection and segmentation is very useful in the
predictive scoring of hormone receptor status in ER-IHC
stained whole-slide images, which helps pathologists to decide
whether a patient should be offered hormonal therapy or other
treatments. The proposed method is based on deep
convolutional neural network, followed by watershed-based
post-processing. The cell detection results are compared and
evaluated objectively against the ground truth provided by our
collaborating pathologists. The cell segmentation results, on the
other hand, are evaluated visually by overlaying the computer
segmented boundaries on the ER-IHC images for comparison.
The automated cell detection algorithm recorded precision and
recall rates of 95% and 91% respectively. The very promising
performances for both the detection and segmentation paves the
way for an automated system for hormone receptor scoring in
