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 →

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 →

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 →

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 →

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 →

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 →

Genera setup: They used eCognition for image recognition; Kodak DC4800; 2 square meter plots; 1.5 meters above the ground with a 90 degree angle (as opposed to the 45 degree in the digital repeat photography paper); 3.1 megapixels; Used automatic … Continue reading →

Additional Measurements: Soil moisture, temperature, air temperature, relative humidity, Solar radiation flux (with a pyranometer), amount of precipitation, from the RGB the calculated “amount of greenness”, percent aerial cover of plants with SamplePoint (Some kind of software, I have to … Continue reading →

Possible research for fault tolerance and robustness in autonomous systems: Agent based architecture: Though a three tier architecture is predominant in autonomous embedded systems, the agent approach could work because of 1.Avoiding semantic mismatch given that all agents have the … Continue reading →
