Build a greener future with biochar and lime-infused cow dung bricks If you're looking for an eco-friendly and sustainable way to build, consider making cow dung bricks. Not only are they a low-cost alternative to traditional fired clay bricks, but they also use waste materials like cow dung and biochar. Biochar is a charcoal-like substance that is made by burning organic materials in the absence of oxygen. It is a byproduct of biomass pyrolysis, a process that turns plant waste into energy. Biochar is known for its high carbon content, which makes it an excellent soil amendment and a potential solution to reducing greenhouse gas emissions. To make cow dung bricks with biochar, you will need the following materials: 1) Cow dung 2) Biochar 3) Lime or Chona 4) Methi water (Water fermented with fenugreek seeds) Here's a step-by-step guide on how to make cow dung bricks using these materials: Mix the cow dung with biochar and lime in a 2...
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...
