There are a variety of competing methods that have been proposed for obstacle detection and many papers written on such methods. There have been few papers, however, which have offered more than a trivial comparison of the various methods, especially in any analytical fashion. All systems have their drawbacks, and almost all methods are susceptible to problems caused by environmental conditions such as ambient lighting (or lack thereof) or precipitation. A vehicle-mounted optical flow system is unlikely to be successful for static obstacle detection, but that a stereo system is likely feasible for obstacle detection in daylight. Current laser range-based methods have not been proven at highway distances and are too expensive as a solution for consumer vehicle obstacle detection. Laser intensity has been ignored as a potential solution by most researchers. Radar, while an excellent means of detecting vehicles, is an unlikely candidate for detecting small static obstacles because of their relatively low radar cross section. It is likely that multiple detection methods will be necessary for reliability. For example, the combination of stereo and laser shows promise since stereo works well in daylight, and a laser system works best in little or no ambient light.

Detection theory allows one to quantify the ability to discern between information bearing patterns and random patterns that causes confusion in the patterns. In electronics, detection theory is often called signal recovery.

The limit of detection in analytical testing methods is the lowest concentration of a substance that can be reliably detected. Sensitivity refers to how well a method can detect small changes in concentration. Generally, a lower limit of detection indicates higher sensitivity in analytical testing methods.
Some cons of detection methods include the possibility of false positives or false negatives, the potential for invasive procedures or side effects, and the need for regular monitoring which can be inconvenient or costly. Additionally, detection methods may not always be able to detect early stages of a disease or condition.

Alternative methods to western blot for protein detection and analysis include enzyme-linked immunosorbent assay (ELISA), immunohistochemistry (IHC), mass spectrometry, and protein microarrays. These methods offer different advantages such as higher sensitivity, multiplexing capabilities, and the ability to analyze protein interactions.

Phase detection and contrast detection are two common methods used in autofocus systems. Phase detection is generally faster and more accurate than contrast detection because it measures the difference in phase between two light paths to determine focus. Contrast detection, on the other hand, analyzes the contrast between adjacent pixels to find focus, which can be slower and less accurate, especially in low light conditions.
