CSIRO’s Biotech Imaging team, who specialise in developing software to analyse images automatically, worked with a UK personal care products company to find a way to objectively test how well their hair removal products work.
Hair counting is often done manually by human assessors.
“It’s a boring job and results are prone to errors and variations between different people,” Dr Pascal Valloton, Leader of Biotech Imaging at CSIRO said.
“Our software uses images captured by a small flatbed scanner pressed onto the skin. The software crunches the numbers to analyse the image of skin and hairs.
“Then, almost instantly, it reports information about the length and number of hairs in the picture. “You can compare the results with earlier images to see if hair is growing quickly or slowly or has been properly removed by, say, a depilatory cream.”
“The software can even detect hairs that people find hard to see and it’s not confused by variations in background skin colour or texture,” Dr Vallotton said.In the language of image analysis, a hair is called a ‘linear feature’. There are many ways of detecting linear features but this software uses algorithms that exploit some special things about hairs, like their relative straightness.
“The software can even detect hairs that people find hard to see and it’s not confused by variations in background skin colour or texture,” Dr Vallotton said.
The linear feature algorithms the software uses are similar to those developed by the team for medical research to measure the branching structure of nerve cells and to find the boundaries of fat cells.
The hair counting methods, the hardware and the algorithms are described in the November issue of Skin Research and Technology journal.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
