Patient discussion about region of interest

Q. Any idea on how to meet people who suffer from alcoolism in my region?

A. if you look for an AA meeting near your home- that should not be a problem- just "google" it. or ask your doctor to reffer you to the nearest clinic.
take care! and good for you on that big step!

Q. Is there any problem, if an arachnoid cyst ,2cmx1.5cm size, rostral to cerebellar region left untreated? symptoms: repeated headaches, twitching of muscles, tiredness

A. An arachnoid cyst that leads to symptoms usually needs treatment. Mild symptoms as you suggested are ok to left untreated however gradual onset of new symptoms may arise such as seizures, paralysis and other complications, therefore once symptoms occur one should consider treatment.

Q. experiencing sharp pain in my right kidney region... pain is acute and doesnt radiate... recently PE left lung have been taking warfrin, panadiene forte, two kinds of cholesterol/triglycerine reducing meds and champix quit smoking medication... recently tests showed the hight cholesterol and triglys' levels and also a swollen liver... pain is not in my liver area... past pain in this kidney recurrent but never as bad. always dull.. many years ago had a uti, which caused high protiene levels.. very bad at finishing anti-biotics... recently had tonsilitis.. This hurts and is tender to touch but does not bring on sharp pain when touched, sharp pain comes and goes after taking pain relief

A. Go to see a doctor - although its tempting to make the diagnosis over the net (I have several ideas about what it might be), it sounds like serious, especially if you had a PE lately - it could be a thrombus in the vein of the kidney, or maybe a stone (sounds like that according to the description of the pain). However, as I said, making the diagnosis without even seeing you isn't the wisest thing to do.

Take care,

In the equations, n and m indicate the size of the input image I, but considering only the pixels that belong to the region of interest; i and j represent the position (row, column) of the current pixel in the image; R, G, and B indicate the channel value in RGB colour space; H, S, and V represent the channel value in HSV colour space; L, a, and b represent the channel value in [L.sup.*][a.sup.*][b.sup.*] colour space; E is the edge image; VE is the set of vessel edges within the region of interest, whereas [bar.VE] are the nonvessel pixels.
Meanwhile, depth of field spreads out the region of interest and makes it considerably sharper to clearly view and locate any possible flaws.
Finally we found some methods to resolve these problems and proposed the region of interest detection model based on visual attention and threshold segmentation (VA-TS) in high spatial resolution remote sensing image.
