Scientific Digital Imaging And Its Many Uses

Scientific digital imaging is merely the use of digitally enhanced image processing, or image acquisition, for scientific purposes. It is simply the process of creating images, be they retrieved from a physical scene or illustration, and processing, compressing, storing or displaying them. In science, this form of technology proves very useful.

It was primarily invented during the 1960s and 1970s in order to avoid the usual pitfalls and shortcomings of average cameras. The improvements were implemented and used for military and scientific missions. This upgrade led to some greater enhancements and greatly benefited the use of cameras that were used for capturing data to study.

The main idea of this process is that it allows the implementation of complex algorithms for image processing, therefore offering a more difficult level of execution at the simplest of tasks that would be impossible for analog mediums and the like.

Any image can be created from an actual physical scene through the use of a camera. Similar devices can be used, such as analog mediums, photographs, film, paper or scanners. Scenes can also be conveyed by mathematical formula or a geometric model, also known as image synthesis or rendering.

This extracted data are used in hospitals to treat patients. Law enforcement uses them in forensic science to solve crimes. Scientists use them to further expand their knowledge through visual evidence. Such things can help patients at hospitals who are deathly ill and need their doctors to obtain visual evidence that concerns their condition. Law enforcement, the FBI and governmental officials can use it to identify criminals or examine evidence in a more thorough and precise method.

The actual processing of the data is merely when a computer is used to process images through advanced technology. For certain types of research to ensue, this must occur. It was developed in the 1960s at several different facilities of science that worked on satellite technology among many other things. The fact that it is one of the most convenient and inexpensive forms of technology makes it a popular, if not the most popular, method to use.

The uses of the technology ranges from pattern recognition, feature extraction and signal analysis to classification. It uses techniques like pixelization, linear filtering, principle components analysis, wavelets and neural networks. Computer chips convert data from censors into color. They can also correct the pictures themselves.

This type of advanced technology currently also works in common intelligent transportation devices such as Automatic Plate Recognition and Traffic Sign Recognition. It can also alter and airbrush images, as is popular in the service of magazines, modeling agencies and presently even the everyday photo studio. In vivo 3D imaging is also helpful in studying animals and other living organisms through visual images.

The Society for Imaging Science and Technology, or the IS&T, is a society that promotes scientific research and education. The first film to use digital imaging processing was “Westworld” in 1973. It is merely the art of creating, studying, altering and researching certain data and drawing additional wisdom from them.

Science and God’s Existence, Do They Agree Or Disagree?

Some people think that when a person studies science deeply, he/she will probably find out that God does not exist. Far from the truth! One day a young science student in a biology practical lesson put iodine solution on cooked starch and saw a blue-black color. He got excited and went home to disprove the existence of God to his Christian grand mother who used to talk about the presence of God!

Actually, the more one learns about science, the deeper he/she gets to believe that God exists! Who provides the forces that hold the stars and moon around the sun? How do electrons manage to keep around the atom? How does the brain efficiently and effectively coordinate all the activities of the body? Who can fully explain the power behind the engine of life, the pumping heart, which does not wear out or get tired for all the years of one’s life, a part from the one who created it? A deeper search attempting to answer some of the above questions will lead someone to believe that there must be a supernatural being behind all creation and life processes.

Today’s technological advancement involving heart transplantation, test tube fertilization, technology literacy and many more provides more understanding of the existence of God, the author of all wisdom and knowledge, which he partially gives to his people to contribute to His creation for the benefit of all the people on earth. The wonderful design depicted by nature provides more evidence to prove the existence of a supernatural artist. As one man put it “You need more faith to believe that there is no God than to approve His existence.”

Many great scientists who lived before us and who established the foundation for the modern Science died after confessing that God exists! Armstrong, the first Scientist to visit the moon appreciated the existence of God when he landed on the moon. Sir Isaac Newton, the found of the acceleration due to gravity died when he was a Christian and after accepting that the living God does exist. Darwin, the father of evolution confessed that “to believe that an eye, together with all its parts uniquely and corporately joined together was as a result of chance is the absurdity of the highest order”.

The best laboratory to prove the existence of God is not that of Chemistry, Biology or Physics but one’s own life. I have proved this by my own life which I surrendered to Him at an age of 20 and he transformed me from a sinful, hopeless and destructive life to the present new, optimistic and constructive life. The creator of heaven and earth, who formed you, has the power to transform you! Because He made you, He has the power to mend you! He is the creator of all the visible and invisible (Col 1:16) and therefore, the best consultant for prospective scientists and researchers who want to discover more invisible things in Science and life. If you are unable to prove His non-existence then desist from denying His presence. If you cannot defeat them its better you join them.

Virtual Education in The K-12 Years – Learning, Retention and Technology

“During a learning episode, we remember best that which comes first, second best that which comes last, and least that which comes just past the middle!”

Sousa, D. (2006), How the Brain Learns, Corwin Press.

Simply stated, learning takes place when we are offered information that our brain deems important in the moment to take on. Learning can take place anywhere, for any reason, at any time when the brain is receptive to outside stimulation. Retention is a different issue altogether yet is connected to successful learning episodes to varying degrees as the brain sees fit.

Learning occurs when:

o The learner interacts with the environment and acquires skills and information.

o We find ourselves requiring information to help make sense of a situation we are faced with.

o Meaning is needed in order to make sense of new surroundings experiences or emotions.

It becomes clear that learning is not restricted to a single environment labeled “school”. It also is very apparent that the “school” cannot possibly emulate every circumstance that a person may come across in other environments. We perhaps need to consider the ramifications of conditioning our children to grow up believing that “learning” predominantly happens in schools.

Retention: What is it?

Retention is the process where the long term memory stores information that can be later retrieved accurately for a specific purpose. The process of retention is not an exact science and a little unpredictable in it’s occurrence.

Keys to more successful retention:

o Attaching sense and meaning to a learning experience will improve retention success.

o Giving the learner time to “rehearse” new information . Rehearsal is geared towards having the learner process the information in numerous ways.. Repeating the process in it’s entirety supplies meaning to the experience and enables the brain to make sense of it also.

What retention is NOT:

Retention is NOT learning. Learning can occur yet the information learned in the moment may not be retained. For example you may remember a phone number until you no longer need it. This could be 5 minutes or 5 days. However you are in the position of learning it initially.

Becoming aware of learning as an integral part of being human can bring us all closer to the realization that there are a myriad of answers to the question of “how ” to educate ourselves. Moving away from “conditioning” people to “school based” learning could be a huge step forward. To be open to “learning all the time” will provide more people learning opportunities best suited to their particular style of learning. It has the potential to impact retention in an enormous way.

Technology in the home has the potential to bridge the gap and change the way we condition ourselves in regards to where and when we learn. Should we choose to embrace the radical change technology can bring to education we may begin to see the full potential of the human brain

The fabulous part is we all free to choose!
