ABSTRACT: In this paper, we propose to segment color images of natural scenes by pixel clustering in different color spaces in order to compare the performances of the color spaces. Eight color spaces are evaluated, including perceptual and non-perceptual color spaces. The clustering methods applied in this work are k-means and its extensions. Segmentation results are evaluated by calculating the degree of matching with the benchmark created by manual labeling, and visual evaluation is also applied as a reference. A series of experiments were designed and conducted. Results show that the performances of the color spaces are dependent on the scenes, and it is possible to choose a proper color space manually for a specific image scene segmentation task according to the data dependency patterns analyzed from the experiment results. Key words: color image segmentation, natural scenes, color spaces, k-means clustering

    I have reviewed your conversation with Mr. Bradley Stonefield, and will begin putting together a few recommendations based on the business strategy that was presented last week to increase work performance. In addition, I will take a look at the alignment of performance management framework to the organizational business strategy, the job analysis process to identify the skills needed, the methods used for measuring the employees skills, and the approach for delivering an effective performance review. I know that Mr. Bradley Stonefield will be at a -$50,000 within the first year of business as well as 25 newly hired employees. Furthermore, it is critical to have a plan in place to maximize the company’s performance and to have less than the 10% turnover rate that Mr. Stonefield predicts.…

    The Northwest Coastal Indians, Kwakiutl, lived in what is now Alaska along the Pacific Ocean down the coast to Northern California. The environment was very diverse and often extreme which included a rugged strip of land with small islands, deep inlets, inland rivers and lakes, deep fjords, and wide and narrow beaches. Mountains rise to the shore in many places. Spruce, cedar, and fir forests dominated the area supplying endless amounts of wood. All the people lived near the water and relied heavily on the water for survival. Temperatures were moderate, which allowed the people to fish all year. There was access to the Pacific Ocean for fishing and collecting food like clams and shellfish. Salmon was the most important food.…

    Up until a week ago I thought that the states ideas of “kindergarten readiness” were just political lip service, but last week my opinion changed. I was in the car listening to an interview on NPR (sadly I do not remember the woman’s name) about a new program called Washington Kindergarten Inventory of Developing Skills, or WaKIDS. This year is the pilot season for this program. The interview was also on the up and coming mandate the child care workers, and preschool teacher have a Bachelor’s degree. This mandate will go into effect in 2013 in Washington State.…

    The Iks

    • 607 Words
    • 3 Pages

    In the essay “The Iks”, author Lewis Thomas tells the story about the small tribe of hunters in Uganda who had to struggle to live with others after they were forced by the government to give up their living and working area and move to the poor hills and become farmers. Because of this, the Iks did not know how to live together, and they made each other’s lives very miserable. The individual Ik was selfish and heartless and cared for no one but himself. They didn’t share things with each other and found joy in the other’s misfortunes. They even went as far as to let their children go on their own and take food from the elders. To make things worse, an anthropologist, who hated the Iks, decided to study them for two years to write a book about them. Thomas thought the behavior of the Iks was unmoral and animalistic. He then went on to say that he now sees their behavior as being similar to small groups such as a gang and large groups such as cities and nations. I find that Thomas’ comparison of the Iks’ behavior to some small groups to be unreasonable, whereas I can see the similarities between their behavior and that of larger groups like cities and nations.…

    Imagine a society where your only friend is yourself. In Northern Uganda lies a tribe called the Iks where everyday life is a selfish struggle to survive. Its a society in which morals and ethics do not apply because it was considered as a weakness. Its a society where men treat one another like animals. In the essay “The Iks” by Lewis Thomas, he discusses how each selfish individual Ik displays similar characteristics as groups in general. Though this theory is extreme, it is true. This can be seen in small groups such as gangs to larger societies such as nations.…
