    Visual content acquisition is a strategic functional block of any visual system. Despite its wide possibilities, the arrangement of cameras for the acquisition of good quality visual content for use in multi-view video remains a huge challenge. This paper presents the mathematical description of trapezoidal camera architecture and relationships which facilitate the determination of camera position for visual content acquisition in multi-view video, and depth map generation. The strong point of Trapezoidal Camera Architecture is that it allows for adaptive camera topology by which points within the scene, especially the occluded ones can be optically and geometrically viewed from several different viewpoints either on the edge of the trapezoid or inside it. The concept of maximum independent set, trapezoid characteristics, and the fact that the positions of cameras (with the exception of few) differ in their vertical coordinate description could very well be used to address the issue of occlusion which continues to be a major problem in computer vision with regards to the generation of depth map

    Background: Water quality is a term used to describe the chemical, physical, and biological characteristics of water, usually in respect to its suitability for a particular purpose. Water is said to be polluted if there is an excess, whatsoever, in the values (concentration levels) of the physical, chemical, biological or radioactive properties that have a negative effect on human health.Methodology: Twenty different Areas within Jos Metropolis were selected by simple random sampling for the research, Samples of water were drawn from wells in these areas in duplicate through simple random sampling selection of the wells giving a total of forty different sampled waters and the physical, chemical and biological analysis of the water was done using standard methods.Result: All the wells had turbidity greater than the acceptable value of not more than 5.0 NTU with 19(47.5%) wells having values as high as 20-29 NTU and 2(5%) wells with values of 40-49 NTU. The PH level for all the wells were within the normal range but the nitrite above the normal range in most (82.5%) of the wells except in 7(17.5%) wells that had values between 0.01-0.02mg/L. The coliform count was found to be high in all the sampled water with 33(82.5%) wells having values as high as 5-9 coliform count per 100mls of water.Conclusion: Water-related diseases continue to be one of the major health problems globally. Drinking water quality must be within tolerable use-limits for human consumption. In the study conducted, it was obvious that all the wells did not meet the standard requirement for quality drinking water since all the wells had coliform count above the recommended value for Standard Organization of Nigeria(SON), National agency for food drug administration and control(NAFDAC) and World Health Organization(WHO).&#160
