Importance Of Food Quality Evaluation

Food quality evaluation is important to ensure proper control of quality in food industry, lesser prices, longer shelf life and good taste of the food. Human perception is manipulative and accurate. Hence, there is a need for machine perception since it’s a robust and reliable method. For food quality evaluation, sample images with some problem in quality are chosen. Some of the commonly evaluated foodstuffs include:

[1] Non-vegetarian foods like eggs and sea food

[2] Crops and seeds

[3] Fruits and vegetables

[4] Chocolate chip cookies

#Quality evaluation for chocolate chips will depend on number of chips, size of chips with respect to full cookie, area of chips and their distribution throughout the cookie.

Images of various cookies considered for evaluation are given in
