I watched “Bounding Box Prediction” Video and was left with some doubt. Before this, we were taught about Sliding Window Convolutions and how to efficiently execute this operation. My understanding is regarding Sliding Window Convolutions : We train a CNN Model for nxn input(ignore the channels) T…

Hi ashish_learns, The best explanation is can think of is provided in the original yolo paper itself which you can find here . As the authors write: “We reframe object detection as a single regression problem, straight from image pixels to bounding box coordinates and class probabilities”.

Here is how I differentiate the two approaches: Sliding windows subdivides the input image. YOLO does not. Sliding windows runs forward propagation once for each subdivision. YOLO runs forward propagation once. Sliding windows can only locate an object within the one subdivision input to forwar…

Hi! I believe you were comparing the simple sliding windows algorithm with YOLO, not the convolutional implementation of sliding windows , is that correct? The convolutional approach processes the entire image in a single forward pass, similar to YOLO. Could you clarify how this differs from YOLO, an…

My reply above differentiates ‘simple’ sliding windows from YOLO. I feel like Convolutional Implementation of Sliding Windows (CISW) is a bit of an oxymoron, more confusing than helpful. This is because as shown on the video related to the OverFeat paper, there actually isn’t any sliding window in C…

Since both the Convolutional Implementation of Sliding Windows (CISW) and YOLO process the entire image in a single forward pass, could you explain why YOLO is considered faster than CISW?

I did a quick review of the videos from this week and didn’t find a mention of YOLO out performing CISW. If you have one, please provide it. In the absence of that, we can fall back on the comparison provided by the YOLO authors in the v1 paper OverFeat. Sermanet et al. train a convolutional neur…
