Corresponding author. Revised Jan 28; Accepted Feb 3. Abstract Quality inspection of food and agricultural produce are difficult and labor intensive. Simultaneously, with increased expectations for food products of high quality and safety standards, the need for accurate, fast and objective quality determination of these characteristics in food products continues to grow. However, these operations generally in India are manual which is costly as well as unreliable because human decision in identifying quality factors such as appearance, flavor, nutrient, texture, etc. Machine vision provides one alternative for an automated, non-destructive and cost-effective technique to accomplish these requirements.

Image Processing, Analysis and Machine Vision

The pixel values typically correspond to light intensity in one or several spectral bands gray images or colour images , but can also be related to various physical measures, such as depth, absorption or reflectance of sonic or electromagnetic waves, or nuclear magnetic resonance. Examples are: Re-sampling to assure that the image coordinate system is correct. Noise reduction to assure that sensor noise does not introduce false information.

Contrast enhancement to assure that relevant information can be detected.

Scale space representation to enhance image structures at locally appropriate scales. Feature extraction — Image features at various levels of complexity are extracted from the image data. More complex features may be related to texture, shape or motion.

Segmentation of one or multiple image regions that contain a specific object of interest.

Segmentation of image into nested scene architecture comprising foreground, object groups, single objects or salient object parts also referred to as spatial-taxon scene hierarchy , [27] while the visual salience is often implemented as spatial and temporal attention. Segmentation or co-segmentation of one or multiple videos into a series of per-frame foreground masks, while maintaining its temporal semantic continuity. Estimation of application-specific parameters, such as object pose or object size.

Image recognition — classifying a detected object into different categories. Image registration — comparing and combining two different views of the same object.

Image-understanding systems[ edit ] Image-understanding systems IUS include three levels of abstraction as follows: low level includes image primitives such as edges, texture elements, or regions; intermediate level includes boundaries, surfaces and volumes; and high level includes objects, scenes, or events.

Image Processing, Analysis, and Machine Vision:

Many of these requirements are really topics for further research. The representational requirements in the designing of IUS for these levels are: representation of prototypical concepts, concept organization, spatial knowledge, temporal knowledge, scaling, and description by comparison and differentiation. While inference refers to the process of deriving new, not explicitly represented facts from currently known facts, control refers to the process that selects which of the many inference, search, and matching techniques should be applied at a particular stage of processing.

Inference and control requirements for IUS are: search and hypothesis activation, matching and hypothesis testing, generation and use of expectations, change and focus of attention, certainty and strength of belief, inference and goal satisfaction. In addition, a practical vision system contains software, as well as a display in order to monitor the system. Vision systems for inner spaces, as most industrial ones, contain an illumination system and may be placed in a controlled environment.

Furthermore, a completed system includes many accessories such as camera supports, cables and connectors. Most computer vision systems use visible-light cameras passively viewing a scene at frame rates of at most 60 frames per second usually far slower. A few computer vision systems use image-acquisition hardware with active illumination or something other than visible light or both, such as structured-light 3D scanners , thermographic cameras , hyperspectral imagers , radar imaging , lidar scanners, magnetic resonance images , side-scan sonar , synthetic aperture sonar , etc.

Automation means every action that is needed to control a process at optimum efficiency as controlled by a system that operates using instructions that have been programmed into it or response to some activities. Since automated systems are faster and more precise, the automatic qualitative inspections on food and agricultural products have been attracted much interest and reflected the progress of machine vision applications.

Now, applications of these techniques have been widely used for shape classification, defects detection, and quality grading and variety classification etc. For example, Lefebvre et al.

Latter on Kato determined many physical characteristics of fruits and vegetables non-destructively and according to Aleixos et al. Currently non-destructive quality evaluation techniques have gained momentum Iwamoto et al.

These techniques, particularly for fruits and vegetables, are quick and easy to use Jha and Matsuoka Following an explosion of interest during the s, it has experienced continued growth both in theory and application.

Sonka et al. Machine vision is an engineering technology that combines mechanics, optical instrumentation, electromagnetic sensing, digital video and image processing technology.

As an integrated mechanical-optical-electronic-software system, machine vision has been widely used for examining, monitoring, and controlling a very broad range of applications.

It is the construction of explicit and meaningful descriptions of physical objects from images Ballard and Brown and it encloses the capturing, processing and analysis of two-dimensional image Timmermans However, in another study by Sonka et al.

Nevertheless we can say that the computer vision technology not only provides a high level of flexibility and repeatability at a relatively low cost, but also, and more importantly, it permits fairly high plant throughput without compromising accuracy.

Applications of these techniques have now expanded to various areas such as medical diagnostic, automatic manufacturing and surveillance, remote sensing, technical diagnostics, autonomous vehicle, robot guidance and in the agricultural and food industry, including the inspection of quality and grading of fruit and vegetable. It has also been used successfully in the analysis of grain characteristics and in the evaluation of foods such as potato chips, meats, cheese and pizza.

Crowe and Delwiche a , b have developed a machine vision system for sorting and grading of fruits based on color and surface defects. Tao et al. Computer vision systems provide suitably rapid, economic, consistent and objective assessment; they have been used increasingly in the food and agricultural industry for inspection and evaluation purposes Sun They have proved to be successful computer vision system for the objective measurement and assessment of several agricultural products Timmermans Over the past decade advances in hardware and software for digital image processing have motivated several studies on the development of these systems to evaluate the quality of diverse and processed foods Locht et al.

Computer vision has long been recognized as a potential technique for the guidance or control of agricultural and food processes Tillett The majority of these studies focused on the application of computer vision to product quality inspection and grading. Traditionally, quality inspection of agricultural and food products has been performed by human graders. However, in most cases these manual inspections are time-consuming and labour-intensive.

Moreover the accuracy of the tests cannot be guaranteed Park et al.

By contrast it has been found that computer vision inspection of food products was more consistent, efficient and cost effective Lu et al.
