Hello, what programs can be used for biometric analysis of plants? I only know "STATISTICA". Are there simple and convenient to use?
I am not sure if this may be of help, but interestingly there seems to be very little information in the field of plant biometrics. Weird!Hello, what programs can be used for biometric analysis of plants? I only know "STATISTICA". Are there simple and convenient to use?
Biometric identification is a pattern recognition based classification system that recognizes an individual by determining its authenticity using a specific physiological or behavioural characteristic (biometric).
In contrast to number of commercially available biometric systems for human recognition in the market today, there is no such a biometric system for plant recognition, even though they have many characteristics that are uniquely identifiable at a species level.

In recent years, various approaches have been proposed for characterizing leaf images. Most of them were based on a global representation of leaf peripheral with Fourier descriptors, polygonal approximations and centroid-contour distance curve.
It appears that it makes no difference how microtubules are arranged for greatest efficiency.In animal cells, microtubules radiate outwards from an organelle in the center of the cell called a centrosome, which is a microtubule organizing center (MTOC). The cells of plants and fungi do not have centrosomes, and instead the nuclear envelope—the membrane surrounding the cell’s nucleus—is an MTOC.
This very interesting conversation reveals how intelligent plants really are, considering that they lack neurons or a brain. Sentience already begins at plant level in .It is proposed that, particularly at the distal statocyte pole, microtubules in coordination with cross-bridging structures, act in stabilizing the polar arrangement of the distal endoplasmic reticulum and, in turn, facilitate an integrated function of amyloplasts, endoplasmic reticulum and plasma membrane in graviperception.
I am not all that convinced about a single origin of living things, I am sure there is a first origin, but there is no suggestion that there must have been only a single exclusive site of origin when there were many very similar sites on earth at that time.What is absolutely incredible for me is that plants and animals, all known life on earth, appear to share a common ancestor. There are three (known) domains of life on this planet: eubacteria, archae(bacteria) and eukaryotes. The latter are again divided into three kingdoms: plants, animals and fungi. So the last common ancestor between animals and plants was some archaic eukaryote, presumably single-celled, probably 3 (give or take) or 3.5 billion years ago.
This demonstrates how easy it is to form several thousand molecules and polymers on earth today , let alone on a planet in environmental turmoil.Why those elements? To find out, Life's Little Mysteries consulted Matthew Pasek, a biogeochemist at the University of South Florida.
How many earthlike planets are there in our solar system?Indeed, while our exploration of the solar system has been nothing short of staggering in terms of the images and scientific data obtained, the worlds we’ve visited beyond Earth all appear to be completely sterile.
If it takes such rare complexity why do we have life on earth in the most inhospitable regions and local environments?The originators of the theory, Peter Ward and Donald Brownlee, explain to Astronomy why they think the development of complex life on other worlds is likely extraordinarily rare.
There is a possibility that life on earth started very early in the probabilistic range of average evolutionary processes on similar planets.Is there life beyond Earth? So far, the silence is deafening.
AI is going to be invaluable in cosmology.There is also a reasonable conclusion that greater attention to artefact searches could hasten the discovery of alien intelligence when similar AI and its machine learning algorithms are applied to the previously recorded SETI searches.
