How to Measure the Quality of Images When You Don't Have Gold Standard Images

What to do When You Don't Have Gold Standard Images to Compare Your Processed Images How to Measure the Quality of Images When You Don't Have Gold Standard Images to Compare In the realm of image analysis and processing, quantifying image quality forms a crucial cornerstone of various methodologies. This is especially true when there's a lack of gold standard images or ground truth to set the benchmark. In such scenarios, we're often left asking: how can we measure image quality objectively or subjectively? Let's delve into this topic with an emphasis on establishing robust and reliable metrics for image quality analysis. Objective Measurement of Image Quality Without Ground Truth Objective quality metrics quantify the difference between two images based on numerical methods. But, how do we assess image quality objectivel...

Navigating the Material Challenges of Cow Dung Brick Making

Material Challenges of Cow Dung Brick Making “From finding suitable binders to selecting the right stabilisers, making high-quality cow dung bricks requires overcoming a host of material challenges” Making cow dung bricks 🐄🧱 can be a sustainable and eco-friendly alternative to traditional building materials. However, there are several 🤔 challenges associated with the production of these bricks that need to be addressed for them to be used in construction. In this article, we will discuss the challenges related to binder, micro...

Watered fermented fenugreek: How it impacts cow dung bricks

🤔 Yes, it's possible that fermented fenugreek mixed with water could increase the rate of the chemical reaction between lime and cow dung material. When fenugreek is fermented, it produces organic acids such as acetic acid and lactic acid, which can act as catalysts and lower the activation energy required for the reaction. Additionally, the fermentation process can produce carbon dioxide gas (CO2), which can react with lime to form calcium carbonate (CaCO3), strengthening the final material. However, it's important to note that the exact effect of fermented fenugreek on the properties of cow dung brick would depend on the specific conditions and concentrations used. Further research and testing would be needed to fully understand its effects. 💡 ...

Binders that are useful for making cow dung bricks

Discover the secret to making sustainable cow dung bricks with these good binders. Using binders to create bricks out of cow manure is an impossibility for obvious reasons. Cow dung or gobar, in and of itself, already possesses a binding quality. That, however, is not sufficient for the production of bricks that may be utilised in construction work that bears a load. However, in order to guarantee that these bricks will remain sturdy and long-lasting over the course of time, it is possible that a binder or various naturally occurring binding materials will be required. As a result, in this post, we will discuss the significance of b...
