Content based image retrieval is one of the popular image processing field having huge scope for researchers to work out the novel ideas that will produce the promising results. Core phases of CBIR where the research contribution is desired, are feature extraction based on image contents, Similarity measures used for comparison and the performance evaluation. This paper explores each of these phases by contributing into each of them. Feature extraction phase is based on the 8 bins approach that actually works for dimension reduction. Bins are the feature vector components acquiring the image contents. This approach is dealing mainly with color and texture contents of the image. Texture contents are extracted in the form of statistical moments whereas color contents and their role in the system is evaluated by using four color spaces namely, RGB, XYZ, LXY, and L'X'Y' color spaces. Three similarity measures Euclidean distance, Cosine correlation distance and Absolute distance are used to work out the comparison of query and database image features. Performance of bins approach in all four color spaces is evaluated by three parameters PRCP (Precision Recall Cross over Point), LS (Longest String), and LSRR (Length of String to Retrieve all Relevant images).

The hypothalamic melanocortin system composed of proopiomelanocortin (POMC) and agouti-related protein (AgRP) neurons plays a key role in maintaining energy homeostasis. The POMC-derived peptides, alpha-MSH and beta-EP, have distinct roles in this process. alpha-MSH inhibits food intake, whereas beta-EP, an endogenous opioid, can inhibit POMC neurons and stimulate food intake. A mouse model was used to examine the effects of opioid antagonism with naltrexone (NTX) on Pomc and Agrp gene expression and POMC peptide processing in the hypothalamus in conjunction with changes in energy balance. There were clear stimulatory effects of NTX on hypothalamic Pomc in mice receiving low-and high-fat diets, yet only transient decreases in food intake and body weight gain were noted. The effects on Pomc expression were accompanied by an increase in POMC prohormone levels and a decrease in levels of the processed peptides alpha-MSH and beta-EP. Arcuate expression of the POMC processing enzymes Pcsk1, Pcsk2, and Cpe was not altered by NTX, but expression of Prcp, an enzyme that inactivates alpha-MSH, increased after NTX exposure. NTX exposure also stimulated hypothalamic Agrp expression, but the effects of NTX on energy balance were not enhanced in Agrp-null mice. Despite clear stimulatory effects of NTX on Pomc expression in the hypothalamus, only modest transient decreases in food intake and body weight were seen. Effects of NTX on POMC processing, and possibly alpha-MSH inactivation, as well as stimulatory effects on AgRP neurons could mitigate the effects of NTX on energy balance.
