# 1. CrackIT - An imgage proccessing toolbox
## 1.1. Category:
- What type of paper is this?
→ Toolbox, road survey, crack detection and characterization, image processing, pattern recognition
- A measurement paper?
→ efficient
- An analysis of an existing system?
→ The authors proposed a toolbox that applies the available algorithms for image processing including crack detection and characterization.
- A description of a research prototype?
→ To pre-process images, to detect cracks and characterize them into types, based on image processing and pattern recognition techniques, as well as modules devoted to the performance evaluation of crack detection and characterization solutions.

...

- Which theoretical bases were used to analyze the problem?
→ Nevertheless, high-speed image acquisition systems produce very large amounts of data (images) that need to be efficient and accurately processed, to get a reliable assessment about the road condition.

## 1.3. Correctness:
- Do the assumptions appear to be valid? → yes

## 1.4. Contributions:
- What are the paper’s main contributions?
→ Henrique Oliveira

## 1.5. Clarity:
- Is the paper well written?
→ This paper has a clear structure.

# 2. Classifying food images represented as bag of textons
## 2.1. Category:
- What type of paper is this?
→ Food Classification, Bag of Words, Textons
- A measurement paper?
→ effective
- An analysis of an existing system?
→ The classification of food images is an interesting and challenging problem since the high variability of the image content which makes the task difficult for current state-of-the-art classification methods. The image representation to be employed in the classification engine plays an important role.
- A description of a research prototype?
→ This paper points out, through a set of experiments, that textures are fundamental to properly recognize different food items.

...

- Which theoretical bases were used to analyze the problem?
