3.4.1 Color feature extraction Color moments are the measures that describe the color distribution of an image and the central moments are used to describe a probability distribution. Main purpose of color moment is to form the color indexing for image retrieval applications. The color moments are invariant for scaling and rotation. Here, the first three order moments are used as features for image retrieval. Three color moments are calculated for each channel. For example, 9 color moments are calculated for RGB and 12 color moments for CMYK. The color moments encode both shape and color information. It can be computed for each channel in any color model. Color model is a mathematical representation of color. Here, the color is represented …show more content…
Angular second moment (ASM) feature This feature is used to measure the uniformity or energy from an image. Angular Second Moment is very large, if the pixels are very similar. (3.9) 2. Contrast Feature Generally, contrast is defined as a difference between the color and the brightness of an object. Contrast is a measure of intensity or gray level variations between current pixels and its neighbor. (3.10) If the value of i and j are equal, then the cell is on the diagonal. These values indicate that the pixels entirely similar to their neighbor. Here the weight n is also 0. If the difference between i and j is 1, then there is a small contrast between the pixels and the weight is 1. If i and j are differed by 2, then the pixels have more contrast with its neighboring pixels. Here the weight value is 4. The weight and the value of i-j are directly proportional to each other. The value of i-j increases with the weight. 3. Entropy Feature Entropy is a term used in thermodynamics to measure the proximity among the systems or it is used to define the disorder between systems. Higher entropy means greater disorder values. The following equation is used to define entropy: (3.11) 4. Variance
Erik Erikson was heavily influenced by Freud but while Freud was an ID psychologist, Erikson was an ego psychologist. Erikson stressed that the development of the ego depended heavily on personal and social aspects. “According to Erikson, the ego develops as it successfully resolves crises that are distinctly social in nature. These involve establishing a sense of trust in others, developing a sense of identity in society, and helping the next generation prepare for the future” (McLeod, S. 1970). His theory focused on personality development through eight distinct stages. He believed that personality progressed in a stacking or pre-determined manner, this is referred to as the epigenetic principle. One must
Entropy is not a difficult concept to just take at face value, but it is a difficult topic to gain a good understanding of. To do this some background must be given such as the first and second law of thermodynamics. The second law of thermodynamics states that any event that occurs spontaneously must result in an increase in the randomness of lhe syslem. This means that as an ice cube melts the water molecules that it is composed of will progress toward a less ordered arrangement. The leaves that fall from the trees do nol arrange themselves in a pile on the ground because the second law of thermodynamics is against it. Entropy is a concept that most high school chemistry and physics students enjoy learning about because the now have an excuse for having a messy room, they are fighting nature.

Perception is the ability to see, hear, or become aware of something through your senses. The biggest influence we encounter is our self-concept; the way we see or feel about ourselves

The term “entropy” describes a “measure of disorder or randomness in an isolated system” (Dictionary.com). According to the Second Law of Thermodynamics, the entropy of an isolated system will always increase over time. Therefore, disorder and randomness are constantly increasing. Amis drew from both this law and the work of the physicist A.S. Eddington in writing T...

Thermodynamics is the branch of science concerned with the nature of heat and its conversion to any form of energy. In thermodynamics, both the thermodynamic system and its environment are considered. A thermodynamic system, in general, is defined by its volume, pressure, temperature, and chemical make-up. In general, the environment will contain heat sources with unlimited heat capacity, allowing it to give and receive heat without changing its temperature. Whenever the conditions change, the thermodynamic system will respond by changing its state; the temperature, volume, pressure, or chemical make-up will adjust accordingly in order to reach its original state of equilibrium.
I will fund my exhibit through donations and sales. I would reach out to the community, explain my exhibit and ask for donations, but I would primarily generate revenue through selling items related to the exhibit like prints of the works being shown, creative posters, key chains, t-shirts and other mementos. Additionally, I would have bake sales and fairs and other activities of a similar nature.
