Multi-Class Semantic Segmentation of Faces

In this paper the problem of multi-class face segmentation is introduced. Differently from previous works which only consider few classes - typically skin and hair - the label set is extended here to six categories: skin, hair, eyes, nose, mouth and background. A dataset with 70 images taken from MIT-CBCL and FEI face databases is manually annotated and made publicly available1. Three kind of local features - accounting for color, shape and location - are extracted from uniformly sampled square patches. A discriminative model is built with random decision forests and used for classification. Many different combinations of features and parameters are explored to find the best possible model configuration. Our analysis shows that very good performance (~ 93% in accuracy) can be achieved with a fairly simple model

Role of Tourism in Economic Growth: Empirical Evidence from Pakistan Economy

Tourism activities are considered to be one of the major sources of economic growth. It can be regarded as a mechanism of generating the employment as well as income in both formal and informal sectors. Tourism supplements the foreign exchange earnings derived from trade in commodities and some times finance the import of capital goods necessary for the growth of manufacturing sectors in the economy. On the other hand rapid economic growth in the developed economies attracts foreign travels (Business travels), which leads to an increase in the foreign reserve of the country. Over the past several decades, international tourism has been gaining importance in many economies of the world. According to the World Tourism Organisation (2002), expenditures by 693 million international tourists traveling in 2001 totaled US $462 billion, roughly US$ 1.3 billion per day worldwide. In addition, tourists spending have served as an alternative form of exports, contributing to an ameliorated balance of payments through foreign exchange earnings in many countries. The rapid growth of tourism led to a growth of household incomes and government revenues directly and indirectly by means of multiplier effects, improving balance of payments and provoking tourism-promoted government policies. As a result, the development of tourism has generally been considered a positive contribution to economic growth

NUTRITIONAL STATUS IN CHILDREN (1 – 5 YRS) – A RURAL STUDY

Research question: What is the prevalence of protein energy malnutrition (PEM) in 1 – 5 yrs of age and factors associated with it. Objective: 1. To assess prevalence of protein energy malnutrition in children 1 – 5 yrs of age. 2. To identify the socio-economic and cultural factor associated with protein energy malnutrition Setting: Rural Health Training Centre, Jawan, Department of Community Medicine, J N Medical College, Aligarh. Study design: Cross-sectional study Study variable: Nutritional status, sex, family size, caste, social class, literacy status of parents. Statistical analysis: Chi-square (÷²) test of significance Result: Overall prevalence of PEM was 56.4% in study population, with higher prevalence in female (58.6%) as compared to males (54.2%). Significant relationship was seen between PEM and sex, social class, caste, literacy status of parents and mother
