Color conveys important information for birds in tasks such as foraging and mate choice, but in the natural world color signals can vary substantially, so birds may benefit from generalizing responses to perceptually discriminable colors. Studying color generalization is therefore a way to understand how birds take account of suprathreshold stimulus variations in decision making. Former studies...

In this chapter we focus on image segmentation techniques for some very special images — textile images. They are generated from the color halftoning technique in textile and printing production lines. In contrast with natural color images, textile images have some very distinctive features: (1) generally there are a few dominant colors in a textile image, whereas there may exist hundreds of si...

Natural food preservation method refers to application of naturally produced antimicrobial compounds that are obtained from plants, animals and microbes to prevent food spoilages microorganism, proliferation and growth of food borne pathogens in food and foods products. Now it is the time of growing interest of many researchers with the application of these natural antimicrobial compounds as sa...

In a previous experiment, we have studied the preference judgement of pictorial images with image experts and naive observers. We asked image experts to improve pictorial images the way they preferred. Then we showed those images to naive observers and asked them for their preferred image. We learned that, to enhance an image, an expert divides it into large zones of interest, which mainly corr...

When analyzing the RGB distribution of colors in natural images we notice that they are organized into spatial structures. This observation is not new, quoting Omer and Werman in [5]: “... when looking at the RGB histogram of real world images, two important facts can clearly be observed; The histogram is very sparse, and it is structured.[...] This is because the colors of almost any given sce...

This study evaluates the effects of polyphenolic extract Cistus incanus, lycopene dye from tomatoes, and betanin red beet on selected parameters model meat products with reduced nitrate contents. The composition activity C. incanus was analyzed, revealing presence elagotannins, flavanols, glycosylated flavanols. We studied dyes as well mixtures growth bacteria characteristic environment: E. col...

Introduction: Natural rewards are essential for survival. However, drug-seeking behaviors can be maladaptive and endanger survival. The present study was conducted to enhance our understanding of how animals respond to food and morphine as natural and drug rewards, respectively, in a conditioned place preference (CPP) paradigm. Methods: We designed a protocol to induce food CPP and compare it ...
