Paper: A Universal and Robust Human Skin Color Model Using Neural Networks

The paper is interested in classifying pixels as skin/no-skin. They use YCbCr color space for their experiments.  They analyse the behavior of this color space with respect to skin color.  The found that the Y dimension does not have a … Continue reading

Paper: Digital Image Classification for Malaysian Blooming Flower

This paper has an impressive related work section.  It describes work done in image processing related to segmentation and Neural Networks.  From the context I believe that the paper only tries to detect one type of flower (The title also … Continue reading

Paper: A visual Vocabulary for Flower Classification

The idea behind this paper is to try to classify objects based on more than one differentiating feature.  The ones they used where colour, shape and texture.  Each feature follows a different process but all end up being vectors.  At … Continue reading

Paper: Automated flower classification over a large number of classes

The problem tackled by this paper is how a combination of features can improve classification on datasets of similar classes.  The work with a flower data set that has large between class similarity and small within class similarity. Before they use the features they … Continue reading

Paper: Delving into the Whorl of flower segmentation

A lot of the assumptions in this paper make me feel that this is not the direction where we should be headed. They assume that all the pictures they analyse contain a flower.  For them someone has already classified the pictures as … Continue reading

Paper: Use of digital webcam images to track spring green-up in a deciduous broadleaf forest

Comments: On thing that caught my eye was the way that they used the color channels.  They calculated an index based on the green spectrum: (2*Green) – (Red+Blue).  In the figures they published it gave a really good measure of … Continue reading

Paper: Use of networked digital camera to estimate net CO2 uptake of desiccation-tolerant moss.

Though this paper is directly related to the use of digital camera in plant ecological studies, it is more focused in the correlation between the data from the digital camera and the measurement of photosynthesis.  Since the objective was this … Continue reading
