When we do processing in ZEN - we like to set out minimum overlaps to match the actual overlap set in the acquisition. Most scientific software like ZEN does not warp the image to correct for these types of artifacts - so you need to choose objectives wisely when depending on ZEN for stitching. Objectives without this correction often exhibit severe pincushion or barrel distortion that makes stitching incredibly difficult unless the software can correct for it. For best performance use an optic that has a ‘Plan’ correction - which means it has a field flatness correction. You don’t mention the objective you are using. Overexposure will also negatively influence any seam correlation so watch out for this (the image above looks like it has quite a bit). There are certain types of tissue that benefit from >30% overlap with low mags like a 10x. Generally the lower the mag of the objective the more overlap you want to acquire. It sounds like you’ve been lucky so far - until now.ġ0% overlap is an absolute bare minimum in my experience - we typically recommend 20% for most tissue at 10-20x mag. Software will always have a tough time with these areas - so minimizing them is key. Sometimes seams line up with areas of the section that have minimal detail, or even completely black areas. That aside, there are plenty of video walkthroughs online to bypass this cost.Here’s the thing about correlation thresholds in stitching - they highly depend on the level of contrast and detail in the overlapping regions. The first two skips are free, however from then on, any further ones do incur a financial cost. There is no hints system, however you can skip a puzzle if it’s too difficult to solve. What they do offer however, is a puzzle-set with a steady learning curve, and something that is balancing on the verge of challenging without being frustrating, which again, fits the objective of Colour Zen appropriately. The puzzles are not overly innovative past the core game loop and they do not present any large amount of variance. It’s certainly one of the many factors that draws you into the overall immersion. The flicking motion to manipulate the coloured shapes on screen simple but oh-so effective. The touchscreen controls are in a word, majestic. That being said, I’m certain everyone would choose to go touchscreen, given the choice. There are non-touchscreen options for the Switch but they are not finely tuned and do not present any options for differentiation. Again, considering the game’s mantra of mindfulness, it’s a great triumph.Ĭolour Zen is primarily suited to touchscreen consoles ie: Switch and Mobile. Not immersed in a conventional escape room sense, but more so that I forgot everything else around me whilst I was fixated on the challenges presented. It’s the kind of soundtrack that I would be looking for on Spotify to listen to whilst at work, or just before I go to sleep.Īmazingly, with all these (minimalistic) parts coming together, there were many times that I lost myself in the game, becoming fully immersed. Additionally, the music another simple, implemented concept, has this major trip-hop vibe which again, fits the overall concept highly appropriately. They serve the game’s greater purpose very well to create a relaxing environment whilst your brain is being challenged. The visuals are simple, but they are attractive and the filling of the screen of differing colours are pleasing for the player to witness. There are a couple of variances that come into play as you progress but on the whole it is deceptively simple. To progress, your final move must fill the screen with the same colour that the boarder is. There is no story or narrative, it is purely a vehicle of 120 puzzles to solve, using the game’s rules which ultimately revolve around combine matching colours to fill the screen. That out of the way, if you haven’t played this before it might be worth a visit, particularly when mindfulness is a large tool for functioning well as a human being. One, its 8 years old and two, it’s freemium (initially free, but then can incur potential costs when the player is drawn in). You’re probably wondering why I’m reviewing this game. Curious to know more, I downloaded it and tried my hand at solving Colour Zen’s puzzles. Most were action/FPS-based, however this one stood out for me. I came across this game from an article my wife sent me, on Switch games that were currently free (or freemium). Well if so, this puzzle game might just be for you.
