1. Basic Image Analysis GUI for Cell Counting and Segmentation Tri Phan, Ravi Shrivastav, Rubina Narang

2. Background - Image processing allows the researchers to perform: analysis, segmentation, enhancement, geometric transformation & visualization. - The challenge is to effectively process and analyze the images in order to effectively extract, quantify, and interpret this information. - The general goal is to understand the information and put it to practical use.

3. Applications - Image processing and analysis has developed into one of the most important fields in biology and medicine for the study of cell structure and its characteristics. - A vital part of the early detection, diagnosis, and treatment of cancer. - Other areas: cell embryology, wound healing, host defense mechanisms and mechanisms of tumor metastasis and invasion.

4. Problem - The raw microscopic images of cells in biology are often prone to artifacts and imperfections. noise at low light levels uneven illumination - Manual counting procedure could be tedious and confusing at times. - Human vision can be easily biased by preconceived notions of objects and concepts.

5. Approach - Using Matlab to develop the GUI that: enhances the image quality by adjusting its contrast and brightness. utilizes spatial filtering, image transformation techniques to segment and quantify the cells. - Techniques to be implemented: Grayscale filter, Overlay, Detect centroids, Watershed filter.

6. DEMO

8. Input Data -User input: microscopic image of cells. -imread() will read and store image data.

9. Results

10. - The final output displays: The final processed image. The number of cells that the GUI can detect. - Export results to excel.

11. Conclusion -Different possible combinations of algorithms and techniques are necessary for a satisfactory result. -Techniques used might not be optimal for some particular type of cell images. -Different type of cell images requires different combinations of algorithms and parameters for better results.

12. Challenges - Many algorithms and techniques have been described in the literature. Which combination will yield the best results? - Imoverlay function. - Measure function.

13. Future works ❖ Analyzing complex overlapped cells in the image (hue saturation value). ❖ Measure function.
