# Technical Data Extraction: Execution Time Comparison
## 1. Image Classification
This image is a **Bar Chart** comparing the execution times of nine different algorithms or systems.
## 2. Component Isolation
### Header/Title
* **Content:** None present in the image.
### Y-Axis (Vertical)
* **Label:** Execution Time /seconds
* **Scale:** Linear, ranging from 0 to 120.
* **Major Tick Marks:** 0, 20, 40, 60, 80, 100, 120.
### X-Axis (Horizontal)
* **Categories:** Nine distinct labels representing different methods.
* **Labels (Left to Right):** Kendall, Spearman, CloudScout, LOUD, AID, HALO, CMMD, KPIRoot, KPIRoot+.
### Main Data Area
* **Type:** Single-series bar chart.
* **Color Coding:** All bars are a uniform light aquamarine/mint green color with black outlines.
* **Legend:** No legend is present as there is only one data series.

## 3. Data Table Extraction
The following values are estimated based on the alignment of the top of each bar with the Y-axis grid markers.
| Algorithm / Method | Estimated Execution Time (Seconds) | Visual Trend Description |
| :--- | :--- | :--- |
| **Kendall** | ~12 | Low baseline. |
| **Spearman** | ~15 | Slightly higher than Kendall. |
| **CloudScout** | ~13 | Comparable to Kendall/Spearman. |
| **LOUD** | ~28 | Significant increase, roughly double the baseline. |
| **AID** | ~117 | **Peak Value.** Highest execution time in the set. |
| **HALO** | ~20 | Sharp decrease from AID, returning toward baseline. |
| **CMMD** | ~84 | **Secondary Peak.** Second highest execution time. |
| **KPIRoot** | ~5 | **Minimum Value.** Lowest execution time in the set. |
| **KPIRoot+** | ~8 | Slight increase from KPIRoot, but still very low. |

## 4. Key Trends and Observations
* **Performance Outliers:** The "AID" method is the clear outlier with the longest execution time, exceeding 110 seconds. "CMMD" is the second most time-intensive method at approximately 84 seconds.
* **Efficiency Leaders:** "KPIRoot" and "KPIRoot+" demonstrate the highest efficiency (lowest execution time), both finishing in under 10 seconds.
* **Baseline Group:** Kendall, Spearman, CloudScout, and HALO form a "middle-low" cluster with execution times ranging between 12 and 20 seconds.
* **Comparison:** The execution time for AID is approximately 23 times longer than the execution time for KPIRoot.
